What is powe factor and types of power fector

Question

Accepted Answer

Power factor is the ratio of real power to apparent power. Types include leading, lagging, and unity power factor.

Power factor is a measure of how efficiently electrical power is being used.
It is calculated by dividing real power (measured in watts) by apparent power (measured in volt-amperes).
A power factor of 1 (or unity) means all the power is being used efficiently, while a power factor less than 1 means some power is being wasted.
Leading power factor occurs when the current leads the voltage, while lagging power factor occurs when the current lags the voltage.
Unity power factor occurs when the current and voltage are in phase.
Power factor correction can be used to improve power factor and reduce wasted energy.
