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 `C`C. `R` and `C`D. only `L` |

Answer» Correct Answer - D When c circuit contains inductance only, then the current lags behind the voltage by the phase difference of `(pi)/(2)` or `90^(@)`. While in a purely capacitive circuit, the current leads the volatge by a phase angle of `(pi)/(2)` or `90^(@)`. In a purely resistive circuit is in phase with the applied voltage. |
