The maximum value of a.c. voltage in a circuit is 707 V . Its rms value is

A

70.7 V

B

100 V

C

500 V

D

707 V

Text Solution

Verified by Experts

The correct Answer is:
C
The root mean square value `(V_(rms))` of alternating voltage is given by
`V_(rms)=(V_(0))/(sqrt(2)),` where `V_(0)` is peak value.
Given, ` V_(0)=707V`
`V_(rms)=(707)/(sqrt(2))=(707)/(1.414)~~500V`
