If the voltage in an ac circuit is reparesented by the equation `V=220 sqrt(2) sin (314 t - phi)`, calculate
frequency of ac

A

`50 Hz`

B

`50 sqrt(2) Hz`

C

`50//sqrt(2) Hz`

D

`75 Hz`

Text Solution

Verified by Experts

The correct Answer is:
A
As `omega = 2 pi F, 2 pi f= 314, i.e. , f=(314)/(2 xx pi) = 50 Hz`.
