power factor is the Cosine of Angle between the Applied
VOltage and current. It directly depends on the Load. If
the load is Inductive then the PF is LAGGING.If the load is
resistive the PF is leading.Power Factor takes value from 0
to 1. Unity Power Factor is the Idealised condition, means
least power dissipated and high effeciency.
It can also be calculated from R/Z and KW/KVA ratings.
