The width of depletion region of a diode:
Correct answer: B. Increases under reverse bias
- A. Increases under forward bias
- B. Increases under reverse bias
- C. Is independent of applied voltage
- D. All of these
Explanation
When the diode is forward biased, the width of depletion region decreases and when it is reverses biased then the width of depletion region increases.

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.
