Answer / gautham
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.

Answer / satish m
It is the ratio of the resistance to impedance.
PF= R/Z.
OR
It is cosine of phase angle between voltage & current.
It can be improved by connecting the capacitors in parallel
to the supply.

Answer / saravanan.n
the power factor of acircuit may be defined as:
(1)the ratio resistance and impedance = r/z
(2)the ratio = watts/voltampers=trepower/apparent
power=V x I x cosQ /V X I
(3)the cosine of the angle of lead or lag current from the
applied voltage
