An `LCR` series circuit containing a resistance of `12 Omega` has angular resonance frequency `4 xx 10^(5) "rad" S^(-1)`. At resonance the voltage across resistance and inductance are `60 V` and `40 V` respectively. Then the values of `L` and `C` are respectively.

A

`0.2 mH, 1//32 mu F`

B

`0.4 mH, 1//16 muF`

C

`0.2 mu, 1//16 mu F`

D

`0.4 mH, 1//32 mu F`

Text Solution

Verified by Experts

The correct Answer is:
1

At resonance
`i = (V)/(R ) = (V_(L))/(X_(L)) , X_(L) = omega L, omega = (1)/(sqrt(LC))`
