    The diagram shows a capacitor C and a resistor R connected in series to an ac source. \[{{V}_{1}}\] and \[{{V}_{2}}\] are voltmeters and A is an ammeter Consider now the following statements I.         Readings in A and V2 are always in phase II.       Reading in V1 is ahead in phase with reading in V2 III.      Readings in A and V1 are always in phase which of these statements are/is correct                [AMU (Med.) 2001]

    A)            I only                                       

    B)            II only

    C)            I and II only                           

    D)            II and III only

    Correct Answer: B

    Solution :

               In RC series circuit voltage across the capacitor leads the voltage across the resistance by \[\frac{\pi }{2}\]
