Answer / mani777
pf is cosine (cos theeta) between voltage and current
pf= real power or reactive power/apperent power
pf=kva/v*i

Answer / dhivyabharathi
It is the ratio of resistance to impedance.cos@=R/z.
| Is This Answer Correct ? | 3 Yes | 1 No |
Answer / ravindra
pf tells that how much amount of power delivered by the
source from their total power. in ac ckts it is Cos(q)=p/vi,
ac ckts have v and i both sinosoidal fuction so it comp up
cos q but in electronic ckts cos q never used . so pf=
delevered power/total power , formula used for electronic ckts

Answer / deepu
power factor is define by an angle by which we mesure active power from apprant power
| Is This Answer Correct ? | 1 Yes | 0 No |
Answer / muthukumar
the cosine of the phaseangle between voltage and current
| Is This Answer Correct ? | 2 Yes | 2 No |
Answer / isk
it is the ratio of real(active) power delivered to the apparent power
| Is This Answer Correct ? | 0 Yes | 0 No |
Answer / irshan memon
It is the measure of how effectively we can consume the electrical energy that totally depends upon the cosine of the angle b/w the voltage and current and this angle become greater than 90 or less than 90 degree depending upon the load that is capacitive load (>90 degree)or the inductive load
(<90 degree)
| Is This Answer Correct ? | 2 Yes | 3 No |
Answer / sajjad
Electric element have angle between phase voltage and phase
current,power factor is cosine of that angle.
