A 100 volt AC source of angular frequency 500 rad/s is connected to a LCR circuit with L = 0.8 H, C=5muF and R = 10Omega`, all connected in series. The potential difference across the resistance is

A

`(100)/(sqrt2)` volt

B

`100` volt

C

`50` volt

D

`50sqrt3`

Text Solution

Verified by Experts

`I _(rms) = ( V _(rms))/( Z) = (100)/( sqrt (R ^(2) + (omega L - (1)/( omega C )) ^(2))) = 10 A = 1 0 xx 10 = 100` volt
