The power factor is the cosine of the phase difference between voltage and current: pf = cos(0, 0;) - It is also the cosine of the angle of the load impedance or the ratio of real power to apparent power. The pf is lagging if the current lags voltage (inductive load) and is leading when the current leads voltage (capacitive load).
