The net charge on n-type material is____________________?
Correct answer: D. Neutral
- A. Positive
- B. Negative
- C. Both positive and negative
- D. Neutral
Explanation
An n-type semiconductor has extra electrons as majority carriers, but the donor ions left in the lattice are positively charged, so the positive and negative charges balance overall. Students often choose b because they focus only on the added electrons and ignore the oppositely charged ionized donor atoms.

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.
