    What will be the phase difference between virtual voltage and virtual current, when the current in the circuit is wattles [RPET 1996]

    A)            90°

    B)            45°

    C)            180°                                         

    D)            60°

    Correct Answer: A

    Solution :

               If the current is wattless then power is zero. Hence phase difference \[\varphi ={{90}^{o}}\]
