Q. An alternating $e$mf is applied across a parallel combination of a resistance $R$, capacitance $C$ and an inductance $L$. If $I_{R},\ I_{L},\ I_{C}$ are the current through $R,\ L$ and $C$ respectively, then the diagram which correctly represents the phase relationship among $I_{R},\ I_{L},\ I_{C}$ and source $e$mf $E$, is given by
A)
B)
C)
D)
Explanation
(c) $I_{L}$ lags behind $I_{R}$ by a phase of $\frac{\pi}{2},$ while $I_{C}$ leads by a phase of $\frac{\pi}{2}$
