An LCR circuit contains resistance of 11...

An LCR circuit contains resistance of 110 `Omega` and a supply of 220 V at 300 rad/s angular frequency. If only capacitance is removed from the circuit, current lags behind the voltage by `45^(@)`. If on the other hand, only inductor is removed the current leads by `45^(@)` with the applied voltage. The rms current flowing in the circuit will be :

A

`1.5A`

B

`2A`

C

`2.5A`

D

`1A`

Text Solution

Verified by Experts

The correct Answer is:
B
Since `phi` remain same, circuit is in resonance
`:. I_("rms")=v_(rms)/Z`
`=220/110`
`I_(rms)=2A`
