What is mean by Power factor..

Answer / pragati

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

From the power triangle, we can define power factor as the
ratio of active power and apparent power.

It is also defined as the ratio of resistance and impedance.

What is mean by Power factor..

Answer / pragati

Power factor is defined as the cosine angle between voltage
and current. i.e.,power factor is cos$.

KVA=KW/cos$

To improve power factor,we have to decrease the Apparent
power i.e.,KVA.
