Introduction
:
Electric circuits can be defined as closed or continuous paths in which electric currents are confined and around which electric currents can be caused to flow. Electrical circuits are an essential part of daily living, and may be found in heavy and light industry, commercial installations and operations, and residential applications. Modern life and its many conveniences seem inconceivable without the use of electric circuits.
The total resistance of a circuit is the sum of the individual resistances of the power source, the wiring, and the load. The load resistance is generally much higher than either the resistance of the power source or the wiring. The resistances of the wiring are usually neglected in classroom laboratory experiments. Very rarely is circuit wiring significant in experimental work. In these cases we consider the loads resistances to be the only resistance. Wiring resistance may be considerable in the case of transmission cables, as well as telephone lines, which are many miles long, and we have a lab which investigates and calculates the resistance in such cables and the lost power and energy due to these lengths.
If an arbitrary load of relatively low resistance were connected to an existing power supply or voltage source, an excessive current might flow to the load, causing burn up or other malfunctions with the load and wiring.
The current can be reduced
by reducing the source voltage, but this is not always feasible and is frequently impossible. The resistances of the voltage source or the load could be increased, but these are usually built right into the source or load. Resistances of connecting wires are so low that miles would be needed to increase the circuit resistance by more than a few dozen ohms. A selection of materials for connecting wires might be useful, but a better method would be to creation of a device that is specifically a resistor that can be included with the circuit to give the net or total resistance needed to provide the desired current for the voltage source involved.
In any DC circuit, the total current is equal to the power source voltage divided by the total or equivalent resistance. For a Series Circuit, this is the only current. This means that if the current in some portion of the circuit is known, the total current and the current through every part of the circuit is known. The sum of the voltage drops across the resistors in series is equal to the power supply voltage.
In Parallel Circuits, the total current from the power source divides into different paths as in approaches the parallel branches. The voltage drop across parallel branches is the same for all the branches. If the voltage drop for one branch is known, the voltage drop for all the parallel branches is known.
The sum of the currents in the various branches is equal to the current from the po.
This document discusses resistors in series connections. It defines a series connection as resistors joined end to end so that the same current flows through each resistor. The total resistance of resistors in series is calculated by adding the individual resistances. Examples of series connections include light switches and Christmas lights. Advantages are simpler construction compared to parallel circuits, but problems include any single resistor failure causing the whole circuit to fail and uneven current draw lowering efficiency. A sample calculation finds the total resistance and current for a series circuit with three specified resistors and a given voltage.

Resistor Circuits and Characteristic Curves
Purpose: In this lab we will introduce basic circuit analysis with series and parallel resistor circuits using Ohms Law and Kirchhoff’s laws. We will also introduce characteristic curves and diodes.
Introduction: Ohm’s Law is of general use with circuit elements, with parts of circuits, or with whole circuits. The voltage across a circuit element is equal to the resistance (or equivalent resistance) times the current flowing through the element. (V=IR)
Kirchhoff’s 1st Law of Circuits: The sum of voltages around a closed loop is equal to zero.

The document is an abstract from the International Journal of Electrical Engineering and Technology discussing fault analysis on a three-phase, three-level grid-connected photovoltaic system. It presents models for the key components of the system - the photovoltaic array, three-level inverter, distribution network, and control algorithms. Dynamic models are developed in MATLAB/Simulink to simulate the system and analyze faults. The models account for factors like irradiance and temperature that impact photovoltaic output. Space vector pulse width modulation is used to reduce harmonic content from the three-level inverter. Simulation results are said to verify the effectiveness of the control system under different operating conditions.
1) Kirchhoff's rules, based on conservation of energy and charge, can be used to analyze more complex circuits that cannot be reduced to a single equivalent resistor. The junction rule states that the sum of currents at a junction is zero, while the loop rule states that the sum of potential differences around a closed loop is zero.
2) To solve circuit problems using Kirchhoff's rules, the problem solver draws the circuit, assigns variables to unknowns, chooses current directions, writes equations using the junction and loop rules, and solves the equations simultaneously.
3) Circuits containing capacitors require analysis of how the current changes over time as the capacitor charges and discharges.
The document provides an introduction to basic electronics components and concepts such as series and parallel circuits, resistance, resistors, switches, batteries, short circuits, breadboards, and homework involving common electronic parts. Key points covered include:
- Series circuits have components wired one after another, while parallel circuits have components wired side by side.
- Resistance controls the flow of electricity according to Ohm's Law. Resistors are used to add resistance and reduce current flow.
- Switches open or close circuits to control the flow of electricity. Batteries store and provide electrical power.
- Breadboards are used to prototype circuits and have rows to connect integrated circuit pins. Homework involves typical electronic parts like resistors, batteries

Kirchhoff's junction rule states the sum of currents at a junction is zero, based on charge conservation. Kirchhoff's loop rule states the sum of potential differences around a closed loop is zero, based on energy conservation.

This document provides an overview of circuits and discusses single-loop circuits. Some key points:
- An emf device, like a battery, maintains a potential difference between its terminals by doing work on charge carriers as they flow from the negative to positive terminal.
- In a single-loop circuit with a battery and resistor, the battery drives current through the resistor from high to low potential.
- Using the energy method, the work done by the battery equals the thermal energy dissipated in the resistor, allowing the current to be calculated.
- Using the potential method and Kirchhoff's loop rule, the sum of potential differences around any complete loop must be zero, also allowing the

Resistor Circuits and Characteristic Curves
Purpose: In this lab we will introduce basic circuit analysis with series and parallel resistor circuits using Ohms Law and Kirchhoff’s laws. We will also introduce characteristic curves and diodes.
Introduction: Ohm’s Law is of general use with circuit elements, with parts of circuits, or with whole circuits. The voltage across a circuit element is equal to the resistance (or equivalent resistance) times the current flowing through the element. (V=IR)
Kirchhoff’s 1st Law of Circuits: The sum of voltages around a closed loop is equal to zero.

The document is an abstract from the International Journal of Electrical Engineering and Technology discussing fault analysis on a three-phase, three-level grid-connected photovoltaic system. It presents models for the key components of the system - the photovoltaic array, three-level inverter, distribution network, and control algorithms. Dynamic models are developed in MATLAB/Simulink to simulate the system and analyze faults. The models account for factors like irradiance and temperature that impact photovoltaic output. Space vector pulse width modulation is used to reduce harmonic content from the three-level inverter. Simulation results are said to verify the effectiveness of the control system under different operating conditions.
1) Kirchhoff's rules, based on conservation of energy and charge, can be used to analyze more complex circuits that cannot be reduced to a single equivalent resistor. The junction rule states that the sum of currents at a junction is zero, while the loop rule states that the sum of potential differences around a closed loop is zero.
2) To solve circuit problems using Kirchhoff's rules, the problem solver draws the circuit, assigns variables to unknowns, chooses current directions, writes equations using the junction and loop rules, and solves the equations simultaneously.
3) Circuits containing capacitors require analysis of how the current changes over time as the capacitor charges and discharges.
The document provides an introduction to basic electronics components and concepts such as series and parallel circuits, resistance, resistors, switches, batteries, short circuits, breadboards, and homework involving common electronic parts. Key points covered include:
- Series circuits have components wired one after another, while parallel circuits have components wired side by side.
- Resistance controls the flow of electricity according to Ohm's Law. Resistors are used to add resistance and reduce current flow.
- Switches open or close circuits to control the flow of electricity. Batteries store and provide electrical power.
- Breadboards are used to prototype circuits and have rows to connect integrated circuit pins. Homework involves typical electronic parts like resistors, batteries

Kirchhoff's junction rule states the sum of currents at a junction is zero, based on charge conservation. Kirchhoff's loop rule states the sum of potential differences around a closed loop is zero, based on energy conservation.
2) Resistors can be in series or parallel. Series resistors have the same current and added potentials, yielding a higher total resistance. Parallel resistors have the same potential and varying currents, yielding a lower total resistance.

This document provides an overview of circuits and discusses single-loop circuits. Some key points:
- An emf device, like a battery, maintains a potential difference between its terminals by doing work on charge carriers as they flow from the negative to positive terminal.
- In a single-loop circuit with a battery and resistor, the battery drives current through the resistor from high to low potential.
- Using the energy method, the work done by the battery equals the thermal energy dissipated in the resistor, allowing the current to be calculated.
- Using the potential method and Kirchhoff's loop rule, the sum of potential differences around any complete loop must be zero, also allowing the

Height and depth gauge linear metrology.pdfq30122000
Height gauges may also be used to measure the height of an object by using the underside of the scriber as the datum. The datum may be permanently fixed or the height gauge may have provision to adjust the scale, this is done by sliding the scale vertically along the body of the height gauge by turning a fine feed screw at the top of the gauge; then with the scriber set to the same level as the base, the scale can be matched to it. This adjustment allows different scribers or probes to be used, as well as adjusting for any errors in a damaged or resharpened probe.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELijaia
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.
