    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 \[\frac{\pi }{2}\].
