Vedclass · Answer

(C) From the phasor diagram,it is clear that the current $i_{rms}$ is lagging behind the voltage $E_{rms}$ by a phase angle of $45^{\circ}$.In an $AC$ circuit,current lags behind voltage when the circuit is inductive in nature.This behavior occurs in an $LR$ circuit,where the inductive reactance $X_L$ dominates the capacitive reactance $X_C$ (or $X_C = 0$).It also occurs in an $LCR$ circuit if the inductive reactance $X_L$ is greater than the capacitive reactance $X_C$ $(X_L > X_C)$.Therefore,the circuit could be either an $LR$ circuit or an $LCR$ circuit with $X_L > X_C$.

The vector diagram of current and voltage for a circuit is as shown. The components of the circuit will be
