Power factor is the phase angle difference between Voltage
and current waves. When the power factor low, it draws more
current to maintain the power

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.

Answer / kravi

my be defined as power factor is a apparent power/tru power
(KW/KVA)

Answer / ahir

pawer factor is define as ratio bet. resistance and reactance.....(R/Z)

IT`S ALSO phase diff. bet. vol. & current.....
it may be lagging or leading type,,,

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.

Why the transformers are rated in KVA ? in new view
