    A sinusoidal voltage of peak value 200 volt is connected to a diode and resistor R in the circuit shown so that half wave rectification occurs. If the forward resistance of the diode is negligible compared to R the rms voltage (in volt) across R is approximately

    A)            200                                           

    B)            100

    C)            \[\frac{200}{\sqrt{2}}\]    

    D)            280

    Correct Answer: B

    Solution :

               \[{{V}_{rms}}=\frac{{{V}_{0}}}{2}=\frac{200}{2}=100V\]
