In the series L-C-R circuit , the voltmeter and ammeter readings are

A

`V=100` volt, `I=2` amp

B

`V=100` volt, `I=5` amp

C

`V=1000` volt, `I=2` amp

D

`V=300` volt, `I=1` amp

Text Solution

Verified by Experts

The correct Answer is:
A

At resonance `(V_(C)=V_(L))`
`V=I_(rms)xxR` (here `z=R`)
`V=V_(rms)=100` volt & `I_(rms)=100/50=2` Amp.
