what is power factor ?

Question

Accepted Answer

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.
Inductive loads like motors and transformers have a lagging power factor, while capacitive loads have a leading power factor.
Power factor correction techniques are used to improve power factor and reduce energy wastage.
