The rms value of potential difference V ...

The rms value of potential difference V shown in the Fig.2.42 is

A

`V_0/sqrt3`

B

`V_0`

C

`V_0/sqrt2`

D

`V_0/2`

Text Solution

Verified by Experts

The correct Answer is:
C
In this case, V=`V_0`, when `0letleT/2=0`,when `T/2letleT`
`therefore V_(rms)^2=(int_0^TV^2dt)/(int_0^Tdt)=1/TV_0^2[int_0^(T//2)dt]=V_0^2/2`
or, `V_(rms)=V_0/sqrt2`
