power fator is developing wherever magnetising power
developing, it can not be eliminated ie, in motor
electrical energy is converting mechanical energy through
flux , the production of flux is the cause of reactive power

Answer / prajeesh

Power factor means the leding of lagging currents... It can
be maintained near to unity by using capacitor pannel if
lagging n motor if the current is leading....
