A full-wave rectifier is operating from 50 Hz. The fundamental frequency of the ripple will be:
Correct answer: A. 100 Hz
- A. 100 Hz
- B. 25 Hz
- C. 50 Hz
- D. 200 Hz
Explanation
A full-wave rectifier rectifies both the half cycles of the AC input meaning it conducts twice during a cycle. The output frequency is double to that of the input frequency. The output frequency of a full-wave rectifier is 2 x 50 = 100 Hz.

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.
