Answer / meher deep

p/vi

Answer / hardworker

Powerfactor is defined as the cosine of the angle between
voltage & current.pf=kW/kVA.It is the ratio of power
utilized to the power delivered.pf depends on the type of
load.
If the load is inductive,pf is lagging.
If the load is capacitive,pf is leading.
If the load is resistive,pf is unity.
pf can be found out from the power triangle.

Answer / ramarpandi

cosine angle between voltage& cureent

Answer / avinash gupta

cosine of angle between voltage and current...so cos fi..

it is a ratio of resistance to impedence..cos fi=r/z

its a ratio between active power/apprent power...=vicosfi/vi
=cosfi

Answer / manasa

Power factor is the ratio between active (real) power to
the apparent power i.e
PF = P/(√P2+Q2)

The power factor can also be calculated from the following
equation provided that the phase difference between the
current and voltage have been measured:

PF = Cosφ

Answer / ashok

power Factor is the Cosine of the angle between real
power & apparant power
power factor = KW/KVA

Answer / dave.vimal

PF Is

1.Cosine angle between voltage and current.

2.IT IS THE RATIO OF RASISTANCE AND TOTAL INPEDNCE OF THAT
CIRCUIT AND DENOTED BY COS PHI.
P.F. = R/Z
3.RATIO BETWEEN ACTIVE POWER AND APPARANT POWER IS CALLED
POWER FACTOR.

POWER FACTOR= ACTIVE POWER/APPARANT POWER
= VICOS/VI

If the load is inductive,pf is lagging.
If the load is capacitive,pf is leading.
If the load is resistive,pf is unity.
pf can be found out from the power triangle

Answer / ravikumar.g

The cosine of the angle between line voltage and line
current is known as Power Factor.

The power factor calculating the Formula =

PF = RealPower/Apparant Power

PF = KW/KVA

Answer / naresh

power factor is the cosine of the angle between phase
voltage and phase current
