Maximum efficiency of half wave rectifier is:
Correct answer: B. 40.6 %
- A. 80.6 %
- B. 40.6 %
- C. 70%
- D. 50%
Explanation
The maximum theoretical efficiency of a half-wave rectifier is 40.6% or approximately 41%.In a half-wave rectifier, only half of the input waveform is used to produce the output, and the other half is discarded. This means that the average output power is half of the average input power.

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.
