The document discusses electric field lines and their properties. It provides examples of electric field line patterns for single and multiple point charges. Key points covered include:
- Electric field lines extend radially outward from a positive point charge and inward toward a negative point charge.
- For two charges of the same sign, field lines point from one charge to the other with no lines between. For opposite charges, field lines begin on the positive and end on the negative charge.
- The number of field lines is proportional to charge magnitude. Stronger fields have more closely spaced lines.
- Field lines always meet conductors perpendicularly and the field is zero inside a charged conductor.
6 ohm's law
Ohm's Law (V = IR) describes the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit. The experiment explores this relationship by measuring the voltage and current through a fixed resistor in a circuit as the variable resistor is adjusted to different positions. A graph of voltage versus current for the fixed resistor will yield a straight line, and the slope of the line equals the resistance based on Ohm's Law. The experimental resistance value is then compared to the known constant resistance to calculate the percent error.

ELETRIC FIELD LINES
This document discusses the properties and behavior of electric field lines. It explains that electric field lines originate from positive charges and terminate at negative charges or infinity. The density of electric field lines indicates the magnitude of the electric field - more closely spaced lines correspond to a stronger field. Electric field lines do not intersect and their number is proportional to the magnitude of the associated charge. The document uses diagrams of electric field lines for single and multiple point charges to illustrate these properties.
Lecture19 electriccharge
Electric charge is a fundamental property of matter that exists in two forms: positive or negative. Like charges repel and unlike charges attract. Charge is quantized and conserved within isolated systems. Conductors readily transmit charges through loosely bound outer electrons, while insulators do not transmit charges at all. Charged objects create electric fields that exert forces on other charges according to Coulomb's law. The electric field is defined as the force felt by a test charge placed at a given point. Field lines depict the direction and strength of the electric field. Within conductors, the electric field is zero and excess charge resides entirely on the surface. The field is strongest at sharp points on conductors.
Electric Field Lines | Physics
As electric field, that is, force per unit charge is a vector quantity; it can be used to represent overall effect of electric field in system of electric charges. Similarly electric field can be used in pictorial form to describe the overall intensity of the field.

Electric dipole
An electric dipole consists of two equal but opposite point charges separated by a small distance. It has both an electric field and potential field that can be calculated mathematically. The potential field is easier to find first. An electric field exerts force on other charges, attracting or repelling them. The potential field of a dipole is proportional to the inverse square of the distance, while the electric field intensity is proportional to the inverse cube of the distance from the dipole. The dipole moment, which characterizes the dipole's strength and orientation in space, is defined as the product of the charge and the distance separating the two charges.

Cascaded multicell trans z-source inverters
Cascaded multicell trans-Z-source inverters are proposed to address the problems of high input current and over voltages caused by leakage inductances that are present in traditional high-voltage gain inverters using single transformers or coupled inductors. The proposed inverters use multiple magnetic cells connected in an alternating cascade pattern rather than a single magnetic cell, which allows them to produce the same high voltage gain while keeping currents and voltages in the components low. Simulation and experimental results also show the multicell inverters can step down their output voltage like traditional voltage-source inverters without compromising waveform quality.

L2 electric field, dipoles
This document provides an outline and overview of lecture 2 on electric fields and dipoles. It introduces the concept of electric fields to explain electrostatic interactions without instantaneous action at a distance. Electric field lines are defined to visualize electric fields, with field strength proportional to line density. Dipoles, such as water molecules, have a net electric field due to internal charge separation but no net charge. They experience a torque in external electric fields. Microwave ovens work by causing the rotation of polar water molecules through an oscillating electric field, generating heat through molecular collisions.

The Maxwell bridge is a type of Wheatstone bridge used to measure an unknown inductance in terms of calibrated resistance and capacitance. It has four arms, with the first containing a series resistance and inductance, the third containing variable resistance and inductance, and the second and fourth containing resistances. The Maxwell bridge uses the principle of compensating the positive phase angle of an inductive impedance with the negative phase angle of a capacitive impedance to bring the circuit into resonance, allowing the unknown inductance to be determined from the capacitance.
Diploma i boee u 1 electrostatic and capacitance
- Static electricity is an imbalance of electric charges within a material that remains until the charge is able to move away through a current or discharge. It is contrasted with current electricity which flows through conductors.
- A capacitor is composed of two conductive plates separated by a non-conductive dielectric. It is used to store electric charge electrostatically and has applications in many electronic devices. The capacitance of a capacitor depends on the plate area, distance between plates, and the dielectric material.
- Electric flux is defined as the electric field strength multiplied by the area over which it acts. It represents the number of electric field lines passing through a surface and has units of volt-meters.
Electrical rules
This document discusses electromagnetic laws and rules, including:
- Fleming's left hand rule, which describes the direction of force on a conductor in a magnetic field for motor action.
- Fleming's right hand rule, which describes the direction of induced current in a conductor moving in a magnetic field for generator action.
- Thumb rules and hand rules can be used to determine which law to apply depending on the physical or virtual parameters of the situation.
Ph 101-4
[1] Maxwell's equations describe the fundamental interactions between electric and magnetic fields and how they propagate as electromagnetic waves.
[2] In vacuum, Maxwell's equations simplify and predict that changing electric fields produce magnetic fields and vice versa, resulting in electromagnetic waves that propagate at the speed of light.
[3] The document derives the wave equations for electric and magnetic fields in vacuum, showing that disturbances in these fields oscillate and regenerate themselves as they travel at the speed of light, representing electromagnetic waves.
Electromagnetics
Study of electromagnetics is for electric and magnetic fields. To understand those fields, we need to know the concept of vector and differential operators.
Vector operators
The document defines and provides properties of gradient, divergence, and curl - three important vector operators in multi-variable calculus. Gradient is defined as the maximum rate of change of a scalar function in space. Divergence measures how a vector field spreads out from a point, with zero divergence indicating a solenoidal (non-spreading) field. Curl measures the maximum rotation of a vector field around a point, with zero curl indicating an irrotational (non-rotating) field. Stokes' theorem relates the circulation of a vector field around a closed path to the surface integral of the curl over the enclosed surface.

Emt two-marks
The document provides definitions and formulas related to electromagnetic theory. Some key points covered include:
1. Stokes theorem relates the line integral around a closed path to the surface integral of the curl over the bounded surface.
2. Coulomb's law states the force between charges is directly proportional to the product of their magnitudes and inversely proportional to the square of the distance.
3. Gauss's law for electric fields states the total electric flux through a closed surface equals the enclosed charge.
Line integral,Strokes and Green Theorem
The document defines key concepts related to line integrals of vector fields. It defines a vector as having both magnitude and direction. It then defines a line integral as integrating a function along a line, and defines a vector field as a region where a vector quantity (like magnetic field) assigns a unique vector value to each point. Finally, it discusses the definition of a line integral of a vector field, and three fundamental theorems relating line integrals to other integrals: the gradient theorem relating it to differences of a potential function at endpoints, Green's theorem relating it to a double integral, and Stokes' theorem relating it to a surface integral.
B.tech ii unit-5 material vector integration
This document discusses various vector integration topics:
1. It defines line, surface, and volume integrals and provides examples of evaluating each. Line integrals deal with vector fields along paths, surface integrals deal with vector fields over surfaces, and volume integrals deal with vector fields throughout a volume.
2. Green's theorem, Stokes' theorem, and Gauss's theorem are introduced as relationships between these types of integrals but their proofs are not shown.
3. Examples are provided to demonstrate evaluating line integrals of conservative and non-conservative vector fields, as well as a surface integral over a spherical surface.
Lesson 31: The Divergence Theorem
Gauss's divergence theorem, the last of the big three theorems in multivariable calculus, links the integral of the divergence of a vector field over a region with the flux integral of the vector field over the boundary surface.
Lec 02 2015 electromagnetic
This document is a lecture on vector algebra and electromagnetic field theory given by Prof. Dr. Magdi El-Saadawi to 2nd year electrical engineering students. It covers vector multiplication, including the dot and cross products. It also discusses the gradient of a scalar field, divergence of a vector, and the divergence theorem. Examples are provided to illustrate these concepts.
Divergence theorem
1) Gauss's law relates the electric flux through a closed surface to the enclosed electric charge. It can be used to calculate the electric field from a charge distribution if symmetry is present.
2) The document explores if there is an inverse expression that can locally calculate the charge density from the electric field. It examines calculating the electric flux through an infinitesimally small volume element.
3) By taking the sum of the fluxes through all sides of the small volume element and equating it to the enclosed charge, it derives that the divergence of the electric field equals the charge density divided by the permittivity of free space. This allows locally calculating the charge density from the electric field.
Divergence Theorem by Himanshu Vaid
The document discusses the Divergence Theorem, which relates a triple integral over a solid region to a surface integral over the boundary of the region. It states that for a solid region Q bounded by a closed surface S, the theorem equates the triple integral of the divergence of a vector field F over Q to the surface integral of F dotted with the outward normal vector over S. An example application of the theorem is shown to evaluate a triple integral using a single surface integral instead of multiple ones.
Green's theorem in classical mechanics and electrodynamics
The document discusses applications of Green's theorem in classical mechanics and electrodynamics. It begins by explaining Green's theorem and related theorems. In classical mechanics, Green's theorem can be used to calculate properties like mass, moments of inertia, and determine whether a force is conservative. It also shows how Green's theorem derives Kepler's second law about equal areas being swept in equal times for planetary orbits.
Stoke’s theorem
1) Stokes' theorem relates a surface integral over a surface S to a line integral around the boundary curve of S. It states that the line integral of a vector field F around a closed curve C that forms the boundary of a surface S is equal to the surface integral of the curl of F over the surface S.
2) In Example 1, Stokes' theorem is used to evaluate a line integral around an elliptical curve C by calculating the corresponding surface integral over the elliptical region S bounded by C.
3) In Example 2, Stokes' theorem is again used, this time to evaluate a line integral around a circular curve C by calculating the surface integral over the part of a sphere bounded by C.
Application of Gauss,Green and Stokes Theorem
Gauss' law, Stokes' theorem, and Green's theorem are used to relate line integrals, surface integrals, and volume integrals. Gauss' law relates the electric flux through a closed surface to the enclosed charge. Stokes' theorem converts a line integral around a closed curve into a surface integral over the enclosed surface. Green's theorem converts a line integral around a closed curve into a double integral over the enclosed area. These theorems have applications in electrostatics, electrodynamics, calculating mass and momentum, and deriving Kepler's laws of planetary motion.
Electromagnetic theory
The document discusses electromagnetic theory, including Coulomb's law, electric field intensity, Gauss's law, electric flux density, electric potential, polarization in dielectrics, boundary conditions, Biot-Savart's law, Ampere's circuit law, magnetic flux density, Faraday's law, and motional EMF. Key topics covered include the relationship between electric and magnetic fields, conditions for electric and magnetic fields at boundaries between media, and how changing magnetic fields induce electromotive forces based on Faraday's law of induction.
Vector calculus
This document discusses key concepts in vector calculus including:
1) The gradient of a scalar, which is a vector representing the directional derivative/rate of change.
2) Divergence of a vector, which measures the outward flux density at a point.
3) Divergence theorem, relating the outward flux through a closed surface to the volume integral of the divergence.
4) Curl of a vector, which measures the maximum circulation and tendency for rotation.
Formulas are provided for calculating these quantities in Cartesian, cylindrical, and spherical coordinate systems. Examples are worked through applying the concepts and formulas.
Electric circuits
The document discusses electrical circuits and Ohm's Law. It defines key concepts like voltage, current, resistance and their relationships. Voltage is measured in volts and is the "push" that drives current through a circuit. Current is measured in amps and is the flow of electrons. Resistance opposes the flow of current. Ohm's Law states that current is directly proportional to voltage and inversely proportional to resistance. Circuits can be connected in series or parallel, affecting how current and voltage are distributed.
Electricity (ppt)
This document provides an overview of electricity and electric circuits. It defines key concepts such as current, voltage, resistance, and different circuit arrangements. Some main points:
- Electricity is a form of energy that flows through circuits due to electric charges and potential differences. Current is the flow of electric charges.
- Circuits must be closed loops for current to flow. Components include batteries, wires, switches, and devices. Their symbols are used in circuit diagrams.
- Circuits can be arranged in series or parallel. Series increases overall resistance while parallel decreases it.
- Resistance opposes current flow

A park is a place where there are many trees and plants and also swings for children. It is a place for enjoyment where children and people can go to walk, run, play or sit. A park can be of different size. A park can be big or small. It can have different things because they are made for a different purpose. Some parks have many swings for children. Swings like a merry-go-round, see-saw, slides are placed where all children can enjoy together. Some parks are for adults and they have fitness equipment, walking path and benches for old people. People go to the park for many reasons. Children go to a park in the evening to play with friends. Some teachers and parents also take them to the park for a picnic. Many people go there in the morning or in the evening for a walk to enjoy the greenery and breathe fresh air. Some go in groups to do exercise and yoga together. Some people go there to do activities like reading, painting or cycling. Parks play a very important role in society. They help people to stay healthy and fit. walking on grass and staying around a lot of trees is very healthy. It also reduces stress and makes people happy. People meet their friends and spend quality time. Parks are a safe place for children where there are no vehicles and they can play there safely. Parks also make our society look beautiful and green. Trees are planted here and it is also good for the environment. Today people remove the parks to make buildings and houses. Children play on the road and they are unsafe. Trees are not planted around and this affects our environment badly. We must all have one park in an area and keep it clean and green.

REPORT2- electric and equipotentials
This report describes two experiments measuring equipotential lines and electric fields between parallel plate conductors and concentric cylindrical electrodes. In both experiments, equipotential lines were marked on conducting paper connected to an 8V power supply. The electric potential and estimated field were measured and plotted against the predictions of relevant equations. For parallel plates, the potential graph matched predictions linearly but the field graph was less accurate. For concentric cylinders, both graphs matched predictions closely except for points near the disc due to measurement limitations. The experiments supported the theoretical relationships between electric potential and field.

Phenomenologicalmodelingofviscouselectrostrictivepolymers
This document summarizes phenomenological modeling of viscoelastic polymers. It discusses how polymers respond mechanically to electrical input via electrostriction and how their viscosity leads to time-dependent effects under large electric fields. The modeling approach uses a multiplicative split of the deformation gradient and an additive split of the free energy contributions. Governing equations are based on Maxwell's equations and a constitutive framework describes the material using energy and free energy functions. Evolution equations for viscosity driving stresses are formulated using a Mandel-type stress tensor. The models are applied to polyurethane elastomers, with good fits found using two viscosity elements and a power law evolution law.
Characteristic equation and properties of electron waves in periodic structures
The difference theory of excitation of periodic waveguides is used to derive the characteristic equation for electron waves formed during interaction of an electron flow with forward and counter-propagating electromagnetic waves of periodic waveguides (slowﱹwave structures). The derived characteristic equation describes interaction of electrons and waves in passbands and stopbands of periodic waveguides and contains known solutions for “smooth” slow-wave structures and resonator slow-wave structures near cutoff frequencies as particular cases. Several analytical solutions allowing comparison of amplification and propagation properties of electron waves inside and at the edges of passbands and stopbands of periodic waveguides are found.
Lab questions
This lab report examines the electric field around a conductor using conductive paper. The student sketches the electric field lines and equipotential lines for two point charges and a parallel plate configuration. Most results support the predictions, though some lines are not perpendicular, possibly due to static charge on the paper or interference from the pencil. The density of equipotential lines, electric field lines, and electric field strength are related - as one increases, so do the others. Introducing a hand near the paper would ground it, altering measurements. The introduction outlines measuring electric fields and equipotentials, while the conclusion notes that objectives were met but with some mechanical errors.
Single electron transistor
In the 19th century, Shockley, Brattain, and Bardeen invented the transistor, launching the information age. Moore's law states that the number of transistors that can fit on an integrated circuit doubles approximately every two years. A single-electron transistor consists of a small conductive island connected by tunnel junctions to source and drain electrodes and one or more gate electrodes. Its operation relies on the transfer of individual electrons between the source and drain through the island in a process called single-electron tunneling. Single-electron transistors allow for extremely sensitive electrometry and microwave detection due to their ability to detect the addition or removal of single electrons.

wireless power transfer
Wireless power transfer using weakly coupled magnetostatic resonators can increase power transfer and efficiency compared to magnetic induction alone. By adding capacitors in series with inductors in both the power sender and receiver to create resonant circuits, the power transfer increases by the sum of the quality factors of the two circuits times the sender's quality factor. The efficiency increases by half the product of the quality factors. However, the overall efficiency remains below 50% for all weakly coupled resonant systems. Resonators with a quality factor of 1,000 could transfer power over a distance 9 times the radius of the devices with 10% efficiency.
##Asymmetric Double Quantum Wells with Smoothed Interfaces 2012
This document summarizes a research article that analyzes the wavefunctions and energy states of asymmetric double quantum wells (ADQWs) with smoothed interfaces due to interdiffusion or other static disorder effects. The discreet variable representative approach is used to solve the one-dimensional Schrodinger equation and determine the energy eigenvalues and eigenvectors. The behavior of ADQW states is investigated for different well widths, degrees of interface broadening, and under an external electric field. It is shown that interface broadening changes energy levels in a non-monotonic way but does not strongly distort resonant conditions near energy coupling regions. An external electric field may also help achieve resonant conditions for inter-subband emission.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
