Alternating current and voltage

Question

The peak voltage in the output of a half wave diode rectifier fed with a sinusoidal signal without filter is 10 volt. The d.c. component of output voltage is

Moderate

A

6.84 V
B

3.18 V
C

8.82 V
D

5.24 V

Solution

For half wave rectification
$V_{d . c .} = \frac{V_{m}}{π} = \frac{10}{π} v o l t = 3.18 volt$
