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 correction can be used to improve the efficiency of a circuit.

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 that induces a voltage in the secondary coil.

• Transformers ar...read more

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, such as in solar panels.
