LIGHT DETECTOR USING NAND GATE
This project report describes building a light detector circuit using a NAND gate integrated circuit. The circuit uses a light dependent resistor (LDR) and resistors in a voltage divider configuration to produce different logic levels at the inputs of the NAND gate depending on light conditions. When dark, the LDR has high resistance and the NAND gate output is low, turning off an LED. When light, the LDR resistance drops and the NAND gate output goes high, powering the LED. The circuit exploits how an LDR's resistance changes with light to effectively detect light and dark conditions.

Led blinker
This circuit allows two LEDs to blink alternately using two transistors, capacitors, resistors, and diodes. When the battery is connected, the capacitors begin to charge through the diodes and base resistors. One transistor will turn on before the other, pulling its LED cathode to ground and lighting it. The opposite capacitor then discharges through its diode, turning on the other transistor and lighting the second LED. The capacitors alternate discharging through the diodes, causing the transistors to alternate turning on and off, making the LEDs blink one after the other. Changing the capacitor values changes the blinking timing sequence. Potential applications include railroad crossing signals, bike safety blinkers, and Christmas decorations.

The last stride preceding setting all the T8 LED Tubes is to put a sticker or mark on the plate. It demonstrates that the installation has been conformed to explicitly oblige LED tubes. This permits circuit testers who will replace the tubes later on to know which installations can be utilized for which specific tubes. Once an apparatus has been balanced for Driven, it can never again be utilized for fluorescent or different sorts of tubes. See to it that the name/sticker is on the focal point of the plate or whatever other place where it can without much of a stretch be spotted.

Circuit theory
The document discusses voltage and current dividers, which are basic circuits used to generate a portion of an input voltage or current as an output. A voltage divider uses two resistors connected in series to a voltage source, with the output voltage across the resistors determined by their ratio. Current dividers have parallel branches for current to flow through, with the same voltage across all components. Examples are given of using voltage and current division rules to calculate output voltages and currents.
Current mirror
This document discusses current mirror circuits. It explains that a current mirror circuit outputs a constant current (I_out) that is equal to a reference current (I_ref) regardless of load or voltage variations. It works by using two identical transistors - one sets the reference current while the other mirrors it. Applications include requiring constant current, making multiple current sources from one, and stabilizing current against temperature changes.
Applications Of Clapping Switch
This circuit uses basic electronic components like resistors, transistors, relays, transformers, and capacitors to turn devices like lights, fans, or radios on and off with hand claps. The circuit amplifies the sound of clapping using a transistor and switches a relay to power the device. It can run on 12V voltage from a step-down transformer and be used to save energy by turning devices on only when needed or for home security applications by detecting intruders.
Elect principles 2 voltage divider
Voltage divider circuits use resistors connected in series to a power supply to generate a range of output voltages. The voltage at the output (VT) is calculated using Ohm's law and depends on the values of the two resistors (R1 and R2) and the supply voltage (E). Under no load conditions, VT equals E*(R2/(R1+R2)). When a load is connected, VT remains approximately the same as long as the load current is much less than the divider current.
Elect principles 2 current divider
The current divider principle states that in a parallel circuit, the total current divides up among the branches proportionally to the resistances of each branch. Specifically:
I1 = IT * R2 / (R1 + R2)
I2 = IT * R1 / (R1 + R2)
Where IT is the total current, I1 and I2 are the currents in each branch, and R1 and R2 are the resistances of each branch. This allows simplifying some Ohm's law calculations for parallel circuits with two branches. The principle is only applicable when there are two parallel branches.

Dot convention in coupled circuits
The document discusses dot convention in coupled circuits. It explains that dot convention specifies the voltage polarity at the dotted terminal of a coil. If current enters the dotted terminal, it induces a positive voltage in another coupled coil's dotted terminal; if it exits the dotted terminal, it induces a negative voltage. Coupling can be electrical, through a physical connection, or magnetic, without connection. Electrical coupling is classified as aiding if currents enter dotted terminals, or opposing if one exits and one enters. Magnetic coupling also has aiding and opposing types based on dotted terminal current direction.

Series and parallel connection of mosfet
The parallel connection of MOSFETs allows higher load currents to be handled by sharing the current between the individual switches. Because MOSFETs have a positive temperature coefficient they can be parallel without the need for source resistors.
Physics capacitors w11-l23
A capacitor is a device that stores electrical charge and energy. It consists of two conducting plates separated by an insulating material called a dielectric. When a voltage is applied across the plates, electric charges of equal magnitude but opposite polarity build up on each plate. This creates an electric field within the capacitor. The amount of charge stored for a given voltage is proportional to the capacitance, measured in Farads, which depends on the size, shape and separation of the plates as well as the dielectric material. Capacitors are used widely in electronic circuits to store charge and energy, such as in camera flashes. The basic formula relating capacitance C, charge Q, and voltage V is Q = CV.

Resonance in electrical circuits – series resonance
This document discusses electrical resonance in series RLC circuits. It explains that series resonance occurs when the inductive and capacitive reactances cancel each other out, resulting in a minimum impedance. This is useful for applications that require a stable oscillating frequency, like radio transmission. The document defines key terms like resonant frequency, bandwidth, and quality factor (Q factor). It describes how the Q factor relates the peak stored energy to energy lost, and how a higher Q factor results in a narrower bandwidth.
Lab 4
This document describes an electrical circuits lab experiment on potentiometers, voltage dividers, and current dividers. The objectives are to identify how a potentiometer works and explain voltage and current distribution using the voltage and current divider rules. The experiment involves using a potentiometer, DC circuit board, multimeter, and software to simulate circuits and measure voltages and currents in series and parallel circuits. Key conclusions are that voltage is proportionally divided in series circuits based on resistances, current through a resistor in parallel is proportional to the total current times the resistance ratio, and a potentiometer can be used as an adjustable voltage divider by varying the wiper connection point.
Clap switch
The document describes a clap switch, which is a switch that can turn an electrical circuit on or off through the detection of sound from clapping. It works by using a microphone to pick up the sound of clapping and converting it into an electrical signal, which is then amplified and used to trigger a flip-flop circuit connected to a relay to switch the circuit. The advantages are that it allows controlling devices remotely through sound and eliminates the need for manual switches, while the disadvantages are that clapping can be cumbersome and the circuit may activate to unwanted sounds without proper filtering.
Led chaser
This circuit uses two ICs, including a 555 timer IC, to create a simple LED chaser. The 555 timer IC is configured as an astable multivibrator to generate pulses that drive a Johnson decade counter IC. The counter IC sequentially lights up the LEDs such that each LED remains on for 1 second before the next one turns on, creating a running light effect. A variable resistor can be adjusted to control the speed of the LED chasing by changing the frequency of the pulses from the 555 timer.
Prince jai nproject report

Key components include the 555 timer, resistor, capacitor, transistor, diode, LED, and piezo buzzer. The circuit operates in monostable mode to provide a timed output when the temperature rises above the threshold set by the variable resistor.

early 1871 Belgian inventor Zénobe Gramme invented a generator powerful enough to produce power on a commercial scale for industry.[1]
In 1878, a hydroelectric power station was designed and built by William, Lord Armstrong at Cragside, England. It used water from lakes on his estate to power Siemens dynamos. The electricity supplied power to lights, heating, produced hot water, ran an elevator as well as labor-saving devices and farm buildings.[2]
In January 1882 the world's first public coal-fired power station, the Edison Electric Light Station, was built in London, a project of Thomas Edison organized by Edward Johnson. A Babcock & Wilcox boiler powered a 93 kW (125 horsepower) steam engine that drove a 27-tonne (27-long-ton) generator. This supplied electricity to premises in the area that could be reached through the culverts of the viaduct without digging up the road, which was the monopoly of the gas companies. The customers included the City Temple and the Old Bailey. Another important customer was the Telegraph Office of the General Post Office, but this could not be reached through the culverts. Johnson arranged for the supply cable to be run overhead, via Holborn Tavern and Newgate.[3]
In September 1882 in New York, the Pearl Street Station was established by Edison to provide electric lighting in the lower Manhattan Island area. The station ran until destroyed by fire in 1890. The station used reciprocating steam engines to turn direct-current generators. Because of the DC distribution, the service area was small, limited by voltage drop in the feeders. In 1886 George Westinghouse began building an alternating current system that used a transformer to step up voltage for long-distance transmission and then stepped it back down for indoor lighting, a more efficient and less expensive system which is similar to modern systems. The war of the currents eventually resolved in favor of AC distribution and utilization, although some DC systems persisted to the end of the 20th century. DC systems with a service radius of a mile (kilometer) or so were necessarily smaller, less efficient of fuel consumption, and more labor-intensive to operate than much larger central AC generating stations.early 1871 Belgian inventor Zénobe Gramme invented a generator powerful enough to produce power on a commercial scale for industry.[1]

ELECTRONIC CIRCUIT BREAKER
Here an electronic circuit breaker is designed which is based on the current sensing across a series element typically a CT (current Transformer). The current sensed which is compared against the preset value proportional to the voltage by comparator which is inbuilt in arduino to generate an output that drives a relay through a MOSFET to trip the load very fastly.
The concept of electronic circuit breaker came into focus realizing that the conventional circuit breakers such as MCBs take longer time to trip.
The steadily increasing population has more demand and consumption of electric energy in the market as raised and that of equipment’s used like electrical and electronics are also costlier
So to protect the electrical system from overload or short circuit here is one possibility, which is by ultrafast acting electronic circuit breaker
The electronic circuit breaker is based on the voltage drop across a series element proportional to the load current, typically a low -value resistor.
