Question

instantaneous emf of an a.c source e=200sin314t volt.find the rms voltage.what will be the frequency of the source?

Answer 1

Answer:

by comparing the given eq with standard eq.

we get

E• = 200

Erms = E°/√2....as it is sine function

Erms = 200/ √2

Erms = 100√2

w (angular velocity) = 314

2πf= 314

f= 314/ 2π

f= 50 Hz
