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

Q13MHT CET 2026 · 13 APR · SHIFT 1Medium

Junction Transistor

In common emitter mode of transistor, the d.c. current gain is 20, the emitter current is 7 mA. The collector current is

Show answer and solution

Answer: (a)

$\alpha = \dfrac{\beta}{1+\beta} = \dfrac{20}{21}$
$I_C = \alpha I_E = \dfrac{20}{21} \times 7 = \dfrac{20}{3}$ mA.
So the answer is (a) $\dfrac{20}{3}$ mA.
