MCQ
An alternating emf 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 currents through $R,\, L$ and $C$ respectively, then the diagram which correctly represents, the phase relationship among $I_R$, $I_L$, $I_C$ and source emf $E$, is given by
  • A

  • B


  • D

Answer

Correct option: C.

c
(c) $I_L$ lags behind $I_R$ by a phase of $\frac{\pi }{2}$, while $IC$ leads by a phase of $\frac{\pi }{2}$.
