An Ac voltage `V=V_0 sin 100t` is applied to the circuit, the phase difference between current and voltage is found to be `pi/4`, then
.

A

`R=100Omega, C=1muF`

B

`R=1Omega, C=10muF`

C

`R=410kOmega, L=1H`

D

`R=1kOmega, L=10H`

Text Solution

Verified by Experts

The correct Answer is:
B

`V` function is sin function. `I` function is ahead of `V` function. Hence, the circuit should be capacitive in nature.
Further, `phi=45^@`
`:. X_C=R` or `omegaC=R`
or `C=R/omega=R/100=0.01R`
In option (b) this condition is satisfied.
