Define the different type of power factor with use and values

Question

Accepted Answer

Power factor is a measure of how effectively electrical power is being used. There are three types: lagging, leading, and unity.

Lagging power factor occurs when the current lags behind the voltage waveform.
Leading power factor occurs when the current leads the voltage waveform.
Unity power factor occurs when the current and voltage waveforms are in phase.
Lagging power factor is common in inductive loads like motors, while leading power factor is common in capacitive loads like power factor correction capacitors.
Power factor values range from 0 to 1, with 1 being ideal.
