Lighting semiconductors are electronic devices that emit light when an electric current is passed through them.
Lighting semiconductors are commonly used in LED lights.
They are made of materials such as gallium arsenide, gallium nitride, and silicon carbide.
When an electric current is passed through the semiconductor, it excites the electrons and causes them to emit photons.
The color of the light emitted depends on the ...

I applied via Walk-in and was interviewed in Aug 2020. There were 3 interview rounds.
Power factor is a measure of how effectively electrical power is being used in a circuit.
Power factor is the ratio of real power (in watts) to apparent power (in volt-amperes).
It indicates the efficiency of electrical power consumption in a circuit.
A power factor of 1 means all the power is being used effectively, while a power factor less than 1 indicates wastage of power.

A motor is an electrical device that converts electrical energy into mechanical energy.
Motors are used in a variety of applications, from powering industrial machinery to driving household appliances.
There are different types of motors, including AC motors, DC motors, and stepper motors.
Motors can be controlled using various methods, such as variable frequency drives and soft starters.
Proper maintenance and inspection ...
A star delta starter is used to reduce the starting current of a motor.
The motor is initially connected in star configuration to reduce the voltage across each winding.
After a set time, the motor is switched to delta configuration for normal operation.
The control diagram includes a timer, contactors, and overload protection.
The timer delays the switching from star to delta configuration.
The contactors are used to switc...
DOL starter is used in single-phase induction motors and small three-phase motors.
DOL starter stands for Direct-On-Line starter.
It is used to start and stop the motor directly without any intermediate control.
It is commonly used in single-phase induction motors and small three-phase motors.
DOL starter provides full voltage to the motor during starting, which can cause high starting current.
It consists of a contactor, t...
The resistive load equation is used to calculate the power consumed by a resistive load.
The equation is P = V^2/R, where P is power, V is voltage, and R is resistance.
This equation is used in electrical engineering to determine the power consumption of resistive loads such as heaters and incandescent light bulbs.
The equation can also be rearranged to solve for voltage or resistance, depending on the information given.

Asynchronous motors are used for various purposes due to their simple design and low cost.
Asynchronous motors are commonly used in industrial applications such as pumps, fans, and compressors.
They are also used in household appliances like washing machines and refrigerators.
Asynchronous motors are preferred for their low maintenance and high reliability.
They are also used in electric vehicles and hybrid cars.
Asynchrono...
Transformers are classified based on their construction, purpose, and voltage level.
Based on construction: core type, shell type, and Berry type
Based on purpose: power transformer, distribution transformer, isolation transformer, autotransformer, etc.
Based on voltage level: step-up transformer, step-down transformer, and isolation transformer
Other classifications: single-phase transformer, three-phase transformer, and ...
India has a total installed capacity of over 370 GW as of 2021.
India's power generation capacity has been growing rapidly in recent years
The country has set a target of achieving 450 GW of renewable energy capacity by 2030
India is one of the world's largest producers of renewable energy, with a capacity of over 100 GW
Coal still accounts for a significant portion of India's power generation, but the government is workin
Chopper circuits are used to convert a fixed DC voltage to a variable DC voltage.
Chopper circuits are also known as DC-DC converters.
They are used in applications such as battery charging, motor control, and renewable energy systems.
Chopper circuits use high-frequency switching to control the output voltage.
Examples of chopper circuits include buck converters, boost converters, and buck-boost converters.
