    An alienating voltage given by \[V=300\sqrt{2}\sin \] (volts in connected across a \[1\mu f\] capacitor through an AC ammeter. The reading of the ammeter will be:

    A)  \[10\,MA\]                  

    B)  \[40\,MA\]

    C)  \[100\,MA\]                

    D)  \[15\,MA\]

    Correct Answer: D

    Solution :

    As,       \[{{l}_{rms}}=\frac{{{V}_{rms}}}{{{X}_{C}}}\] \[=\frac{{{V}_{0}}}{\sqrt{2}}\times {{w}_{c}}=15mA\] \[\left( \therefore \,\,{{X}_{C}}=\frac{1}{{{w}_{c}}} \right)\]
