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

1. 20/π V
2. 10/2√2 V
3. 10/π V
4. 10V

Correct answer: 10/π V

Solution

In a half-wave rectifier, the DC component of the output voltage is the average value of the rectified signal. For a sinusoidal input with a peak voltage of 10V, the average value is given by V_dc = V_peak/π, which equals 10/π V.
