On increasing the reverse bias to a large value in a p-n junction diode, current:
Correct answer: C. Remains fixed
- A. Increases slowly and then remains fixed
- B. Suddenly increases and then remains fixed
- C. Remains fixed
- D. Decreases slowly
Explanation
As the reverse voltage is increased from "0", the reverse current quickly rises to its saturation value "10", As the reverse current remains almost constant. Here the resistance offered by the junction is very high of the order of the several mega ohms.

The more specific you are, the faster it gets fixed. A source beats an opinion.

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.
