Answer / viswa

its the cosine angle of voltage and current...

Answer / naresh

power factor is defined as the cosine of the angle between
phase voltage and phase current.

or

power factor = real power / apparent power

Answer / yasir liaquat arain

power factor is the measure of how efficiently a Load uses
Electricty.
or in other words we can say that "How much Energy is
consumed by the Load versus how much the Utility must
providing".
or
power facot = real power/apparent Power
power factor= R/Z
power factor is the cosine angle between Phase Voltage and
phase Current

Answer / thangaraj r

cosine angle between voltage and current

Answer / abhishek goyal

cosq=P/VI
Power factor= KW/KVA
POWER FACTOR= R/Z

ITS ANGLE BETWEEN THE VOLTAGE AND CURRENT
IF COSQ=1 ITS A UNITY POWER FACTOR
