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

Options

A. Only `R`
B. Only `L`
C. `R` and `C`
D. only `C`

Answer

B

Explanation

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.
