In the circuit shown in figureure, the reading of the `AC` ammeter is
.

A

`20sqrt2mA`

B

`40sqrt2mA`

C

`20mA`

D

`40mA`

Text Solution

Verified by Experts

The correct Answer is:
C
`X_C=1/(omegaC)=1/(100xx10^-6)=10^4Omega`
`I_("rms")=V_("rms")/X_C=((200sqrt(2)//sqrt(2)))/10^(4)`
`=0.02A=20mA`.
