Answer / bharatkumar n

Power Factor is the cosine angle between the applied
voltage and the current flow.If the current leads the
voltage(Since the capcitor opposes the rate of change of
voltage, current flows before applying the voltage) it is
leading power factor if currnt lags the voltage (Since the
inductor opposes the rate of change of current, voltage
appears before the current) it is lagging power factor.

Answer / kevin

it is the relation between voltage and current . the
difference is in the capictor has the voltage lagging behind
current . and in the inductive ckt the current lag behind
voltage

when we use neutral line as grounding.
