Asked in FBISE Physics 2022 — Paper 2 2022

In.transistor, the emitter current, is 3.5A and collector current, is 2.35A.What will be the base current?

Correct answer: B. 1.15A

  • A. 5.85A
  • B. 1.15A
  • C. 1.48A
  • D. 0.67A

Explanation

IB =IE −IC Where:( IE ) is the emitter current( IC ) is the collector currentGiven that the emitter current ( IE ) is 3.5 A and the collector current ( IC ) is 2.35 A, the base current ( IB ) can be calculated as: IB =3.5A−2.35A =1.15ASo, the base current is 1.15 A.

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.
