If a half-wave rectifier is used to convert 50Hz AC into DC, then the number of pulses present in the rectifier voltage is:
Correct answer: B. 50
- A. 25
- B. 50
- C. 100
- D. 75
Explanation
The number of pulses per second in a rectified voltage will be equal to the input voltage . AS, the input voltage is 50 Hz, so pulses per second is also 50.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
