Q. 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 approximatelyPhysics Question Image

Solution:

$V_{ rms }=\frac{V_{0}}{2}=\frac{200}{2}=100\, V$
