In a p-n junction diode, the depletion region carries

Correct answer: A. Zero charge.

  • A. Zero charge.
  • B. Infinite charge.
  • C. Positive charge.
  • D. Negative charge.

Explanation

In a p-n junction diode, the depletion region is formed when the free electrons and holes near the junction recombine, leaving behind immobile ions. The region is devoid of free charge carriers, resulting in a net charge of zero. This means the region does not carry a net positive or negative charge, nor does it carry infinite charge. Therefore, the correct answer is that the depletion region carries zero charge.

About PN Junction

A PN junction forms when p type and n type semiconductor regions meet, creating a depletion layer and a potential barrier. The topic covers forward and reverse bias, diode current voltage characteristics, breakdown and rectification, while distinguishing an ordinary junction diode from a transistor formed from multiple junctions.
