When the PN junction is reverse-biased, its reverse current is of the order of:
Correct answer: D. Microamperes
- A. Gigaamperes
- B. Kiloamperes
- C. Megaamperes
- D. Microamperes
Explanation
The reverse current in a reverse-biased PN junction is of the order of microamperes to nanoamperes, indicating a very small current compared to forward bias conditions.

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.
