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\frac{200}{\sqrt{2}}

D

280

Answer

100

Explanation

Solution

E0 = 200 volt

VD.C = V02\frac{V_{0}}{2} = 100 volt
