The maximum efficiency of a half-wave rectifier is:
Correct answer: B. 40.6%
- A. 80.6%
- B. 40.6%
- C. 70%
- D. 50%
Explanation
The maximum efficiency of a half-wave rectifier is about 40.6%. This is because it only utilizes one half of the AC waveform, leading to significant power loss. In contrast, a full-wave rectifier uses both halves of the waveform and has a maximum efficiency of about 81.2%, which is twice that of a half-wave rectifier. The incorrect options either overestimate the efficiency or are closer but still incorrect.

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.
