The process by which the potential barrier of the depletion region can be increased or decreased is called
Correct answer: B. Biasing
- A. Amplification
- B. Biasing
- C. Modulation
- D. Doping
Explanation
Biasing is the process of applying an external voltage or current to a semiconductor device (such as a diode or transistor) to control its operation. By applying an external bias voltage, the potential barrier of the depletion region in a semiconductor device can be increased or decreased.

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.
