Elections remained as minority carriers in the material:
Correct answer: B. P-type
- A. N-type
- B. P-type
- C. Conductor
- D. All of the above
Explanation
In the p-type semiconductor, where there is a deficit of electrons, holes (positively charged vacancies) are the minority carriers. These minority carriers play a crucial role in the conduction of electricity in semiconductors.

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.
