If a half wave rectifier is used to convert 50Hz AC into DC, then the number of pulses present in rectifier voltage is:
Correct answer: B. 50
- A. 25
- B. 50
- C. 100
- D. 75
Explanation
Option A : The number of pulses is 50 not 25.Option: B Rectifiers produce unidirectional and pulsating voltage from an A.C. source, the number of pulses per second in the rectified voltage remains the same as that of input voltage, i.e., here it is 50 Hz.Option C : The number of pulses is 50, not 100.Option D : The number of pulses is 50, not 75.

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.
