In a circuit, the current lags behind the voltage by a phase difference of `pi//2`, the circuit will contain which of the following ?

A

Only `R`

B

Only `L`

C

`R` and `C`

D

only `C`

Text Solution

Verified by Experts

The correct Answer is:
B
When a circuit inductance only, then the current lags behind the voltage by the phase difference of `pi//2` or `90^(@)`. While in a purely capacitance circuit, the current leads the voltage by a phase angle of `pi//2` or `90^(@)`. In a purely resistive circuit current is in phase with the applied voltage.
