what is meant by power factor ?..

POwer Factor is a cos angle between Voltage and current.

 Is This Answer Correct ? 51 Yes 6 No

what is meant by power factor ?..

real power /Uperant power is called PF

 Is This Answer Correct ? 22 Yes 5 No

what is meant by power factor ?..

true power/apparent power

 Is This Answer Correct ? 17 Yes 5 No

what is meant by power factor ?..

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.

 Is This Answer Correct ? 15 Yes 5 No

what is meant by power factor ?..

true power(kw)/apparent power(kva)

 Is This Answer Correct ? 9 Yes 1 No

what is meant by power factor ?..

ration of power utilised and power suppied

 Is This Answer Correct ? 18 Yes 11 No

what is meant by power factor ?..

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.

 Is This Answer Correct ? 8 Yes 5 No

what is meant by power factor ?..

real powere/Apparent power
kw/kva
R/z

 Is This Answer Correct ? 2 Yes 0 No

what is meant by power factor ?..

power factor=real power\apparent power

 Is This Answer Correct ? 2 Yes 0 No

what is meant by power factor ?..

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

 Is This Answer Correct ? 6 Yes 5 No
