Depletion region carries:
Correct answer: B. No free charge
- A. Negative charge
- B. No free charge
- C. Positive charge
- D. Positive ions
Explanation
The depletion region has no free charge carriers due to the recombination of electrons and holes.

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.
