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

Options

  1. AOnly R
  2. BOnly C
  3. CR and C
  4. DOnly L

Correct answer

D. Only L

Step-by-step solution

When a circuit contains inductance only, then the current lags behind the voltage by the phase difference of 2 or 90^ . While in a purely capacitive circuit, the current leads the voltage by a phase angle of 2 or 90^ . In a purely resistive circuit current is in phase with the applied voltage.
