NEET Physics Semiconductor Electronics Questions Solved

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) 2002                          (d) 280

(b) Vrms=V02=2002=100 V
