I applied via Walk-in and was interviewed in Oct 2020. There was 1 interview round.
Power factor is the ratio of real power to apparent power in an AC circuit.
It is a measure of how efficiently power is being used in a circuit.
A power factor of 1 means all the power is being used efficiently, while a power factor of 0 means no power is being used efficiently.
Inductive loads like motors have a lagging power factor, while capacitive loads like transformers have a leading power factor.
Power factor correc...
Types of power include mechanical, electrical, thermal, nuclear, and solar.
Mechanical power is the energy of motion, such as a car engine.
Electrical power is the flow of electrons, such as in a battery or power grid.
Thermal power is the energy of heat, such as in a furnace or geothermal plant.
Nuclear power is the energy released from splitting atoms, such as in a nuclear reactor.
Solar power is the energy from the sun,
A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.
Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.
They consist of two coils of wire, called the primary and secondary coils, wrapped around a magnetic core.
When an AC current flows through the primary coil, it creates a magnetic field th...
