A full-wave rectifier is operating from 50Hz mains. The fundamental frequency of ripple will be?
Correct answer: A. 100 Hz
- A. 100 Hz
- B. 25Hz
- C. 50Hz
- D. 200Hz
Explanation
Full-wave rectification is a type of rectification in which output is obtained for both halves of a.c. Whereas, the frequency of the output is double that of the input. In a full-wave rectifier, the frequency of the ripple is double that of the main frequency. Hence ripple frequency = "100 Hz".

About Rectification
Rectification converts alternating current into unidirectional current using semiconductor diodes. The content includes half wave and full wave rectifiers, bridge circuits, output waveforms, ripple and smoothing with capacitors, with the difference between rectification and voltage regulation kept clear.
