P.F.=COS#= TRUE POWER\APPARENT POWER
FOR INDUCTIVE LOAD INDUCTOR IS USED WHICH OPPOSES THE
CHANGE IN CURRENT IN THE CIRCUIT AND STORES THE ENERGY IN
THE FORM OF CURRENT AND LEAVES IT LATER. HENCE THE CURRENT
CURRENT WAVEFORM LAGS THE VOLTAGE WAVEFORM, AND THE POWER
FACTOR IS CALLED LAGGING./
FOR CAPACITIVE LOAD CAPACITOR IS USED WHICH OPPOSES THE
CHANGE IN VOLTAGE AND STORES THE ENERGY IN THE FORM OF
VOLTAGE AND LEAVES IT LATER. HENCE THE VOLTAGE WAVEFORM
LAGS THE CURRENT WAVEFORM, AND THE POWER FACTOR IS CALLED
LAGGING BUT THE CURRENT LEADS THE VOLTAGE AND HENCE THE
P.F. IS CALLED LEADING P.F.
