Which of the following is not correct regarding Zener diodes?
Correct answer: A. It is used as a half-wave rectifier
- A. It is used as a half-wave rectifier
- B. It is used as a shunt regulator
- C. It is used as an AC voltage stabilizer
- D. Both B and C
Explanation
Zener diodes are used for voltage regulation (shunt regulator, AC stabilizer), not as half-wave rectifiers, which use standard diodes.

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.
