what do you mean by leading power factor & lagging power
factor
Answer Posted / sudheer
power factor is the ratio of true power and apparent power.
when the load is inductive, the inductance tends to oppose
the flow of current, storing energy then realising it later
in the cycle. the current wave forms lags behind the
voltage wave form.
when the load is capacitive, the opposite occurs, and the
current wave form leads the voltage waveform.
