Answer / shri..

The angel between voltage & current.


KW = KVA * Pf

Answer / raj

cosine of the angle between voltage and current

Answer / prabhu

power factor is defined as the ratio of true power to the
Apparent power.

Pf= KW/KVA

Answer / natarajanramkumar

PowerFactor of circuit may be defined as:
a.The ratio of resistance and impedance=R/Z
b.The ratio=Watts/Voltamperes=True power/Apparent
power=V*I*costheta/V*I.

Answer / keerthi

Power Factor means , if power given by E.B, We cannot use
total amount of power which delivered by it, there will be
sum imaginary power . That imaginary power can be called as
Apparent Power. The ratio between Apparent power and Total
power is called as POWER FACTOR and it always be less than
one. We should maintain the ratio is in nearest of 1.
(i.e.,)0.9..
