    An alternating voltage of 141.4V (rms) is applied to a vacuum diode as shown in the figure. The maximum potential difference across the condenser will be

    A)            100 V

    B)            200 V

    C)            \[100\sqrt{2}V\]

    D)            \[200\sqrt{2}V\]

    Correct Answer: B

    Solution :

               \[{{V}_{peak}}=\sqrt{2}\,\,\,{{V}_{rms}}=\sqrt{2}\times 141.4=200\,V\]
