In n-p-n transistor, p works as______________?
Correct answer: C. base
- A. collector
- B. emitter
- C. base
- D. any of above
Explanation
An n-p-n transistor has two n-type regions, the emitter and collector, separated by a thin p-type base. The letter p therefore represents the base. The likely mistake is choosing the collector because it is also a distinct transistor terminal, but its region is n-type in an n-p-n transistor.

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.
