A) only R
B) only C
C) R and C
D) only L
Correct Answer: D
Solution :
When a circuit contains inductance only, then the current lags behind the voltage by the phase difference of \[\frac{\pi }{2}\,\,\,or\,\,90{}^\circ \]. While in a purely capacitive circuit, the current leads the voltage by a phase angle of \[\frac{\pi }{2}\,\,\,or\,\,90{}^\circ \]. In a purely resistive circuit, current is in phase with the applied voltage.You need to login to perform this action.
