Question
relation between voltage and frequency.
 Question Submitted By :: Electrical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
N=120f/P N= speed , f= frequency,P= No.poles

ie: speed directly proportional to frequency
voltage directly proportional to speed

when frequency is reduced generating voltage also reduced

Answer
# 2
The relation betweeen voltage and frequency is:-
V=4.44F*phi*N, F=frequency
N= speed.

Answer
# 3
In case of transformer the voltage is proportional to
applied signal freq. and the voltage transformation ratio
of the transformer.
In case of alternator the voltage is proportional to the
no. of poles, flux per pole and the no. of coils in series
per pole.
 
Is This Answer Correct ?    25 Yes 9 No

Answer
# 4
Ns=120f/P
Here P is no of pole.
speed is proptional to the frequency but frequency is
inersely propotinal to the pole.
