By which process is the depletion region formed around the junction
Correct answer: A. diffusion
- A. diffusion
- B. fusion
- C. emission
- D. fission
Explanation
The depletion region is formed around the junction by the process of diffusion. In a p-n junction, electrons from the n-region diffuse into the p-region, and holes from the p-region diffuse into the n-region. This diffusion of charge carriers creates the depletion region.Incorrect Options and Explanations: (b) fusion - Fusion is not the process by which the depletion region is formed in a p-n junction. (c) emission - Emission is not the process by which the depletion region is formed in a p-n junction. (d) fission - Fission is not the process by which the depletion region is formed in a p-n junction.

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.
