A sinusoidal voltage of peak value 200 volt is connected to a diode and resistor

Sail E0 Webinar

Question

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 Sinusoidal Voltage Of Peak Value 200 Volt Is Connected To ...

Options:

A . 200

B . 100

C . 200√2

D . 280

Answer: Option C
:
C
If half wave rectifier the output voltage is the RMS voltage

= \frac{V_{o}}{\sqrt{2}} = \frac{200}{\sqrt{2}}
