An alternating emf is applied across a parallel combination of a resistance R, capacitance C and an inductance L. If IR, IL, IC are the currents through R, L and C respectively, then the diagram which correctly represents, the phase relationship among IR, IL, IC and source emf E, is given by
A)
B)
C)
D)
Correct Answer:
C
Solution :
IL lags behind IR by a phase of \[\frac{\pi }{2}\], while IC leads by a phase of \[\frac{\pi }{2}\].
