  Re: relation between voltage and frequency.
Answer
# 1
The relation betweeen voltage and frequency is:-
V=4.44F*phi*N, F=frequency
N= speed.

  Re: relation between voltage and frequency.
Answer
# 2
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

  Re: relation between voltage and frequency.
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.

  Re: relation between voltage and frequency.
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.
