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

A

220 V

B

314 V

C

`220 sqrt(2) V`

D

`200//sqrt(2) V`

Text Solution

Verified by Experts

The correct Answer is:
A
The peak value , `(V_0)=220 sqrt(2) = 311 V`
`V_(rms)=(V_0)/(sqrt(2)) = (220 sqrt(2))/(sqrt(2))= 200 V` .
