    Find rms value

    A) 6 A

    B) \[5\centerdot 25A\]

    C) \[8\centerdot 23A\]

    D) \[7\centerdot 52A\]

    Correct Answer: C

    Solution :

    rms value of current, \[I=\frac{{{I}_{0}}}{\sqrt{2}}=\frac{-11.63}{\sqrt{2}}=-8.23\,A\] Negative sign appears as\[\omega L<\frac{1}{\omega C}\].
