Question

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

Answer 1

Answer: (B)

100

Answer 2

(V_r.m.s.) _H.W.R. = $\frac{V_{0}}{2}$ = $\frac{200}{2}$ = 100 volt
