Junction Transistor question from MHT CET 2026 (13 Apr, Shift 1)

Q5MHT CET 2026 · 13 APR · SHIFT 1Easy

Junction Transistor

In transistor amplifier, base emitter junction is forward biased and collector base junction is reversed biased. The current gain is

Show answer and solution

Answer: (a)

A transistor amplifier is usually in CE mode: input current is base current, output current is collector current.
Current gain $\beta = \dfrac{\Delta I_C}{\Delta I_B}$
So the answer is (a).
