  • question_answer
    In a circuit containing an inductance of zero resistance, the e.m.f. of the applied ac voltage leads the current by [CPMT 1990]

    A)            90o

    B)            45o

    C)            30o

    D)            0o

    Correct Answer: A

    Solution :

               In a pure inductor (zero resistance), voltage leads the current by \[{{90}^{o}}\,\,i.e.\,\,\pi /2.\]
