Q.
A sinusoidal voltage of peak value 200 volt is connected to a diode and resistor $R$ in the circuit figure, so that halfwave 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
Explanation
(c) If half wave rectifier the output voltage is the RMS voltage
$= \frac{V_{0}}{\sqrt{2}} = \frac{200}{\sqrt{2}}$
