 Question Submitted By :: Electrical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
The Ratio of Active power o to the Apparent Power is the
power Factor. P.F= KW/KVA
 
Is This Answer Correct ?    44 Yes 7 No

Answer
# 2
PF is the ratio between true power & apparent power./PF is
the angle between voltage & current.

PF in HT side PF=KWH/KVAH
 
Is This Answer Correct ?    20 Yes 5 No

Answer
# 6
Power factor is an angle between the waveform of voltage
and current P.F=cos*
P.F=KW/KVA
 
Is This Answer Correct ?    12 Yes 6 No
Rajkumar
 
Answer
# 7
The cosine angle between voltage and current vectors is called a power factor.


power factor = active power/apparent power.

Note:The power factor is depending up on reactive power. so it is not need on(special) HT side.
 
Is This Answer Correct ?    7 Yes 1 No

Answer
# 8
The phase angle between current and voltage.
The ratio between true power and apparent power.

cos*=kWh/kvah
 
Is This Answer Correct ?    1 Yes 0 No
