Junction Transistor

If transistor having $\alpha = 0.9$ , is used in CE configuration, then for a change of $0.4$ mA in base current, what will be the change in collector current?

Show answer and solution

Answer: (a)

$\beta = \dfrac{\alpha}{1 - \alpha} = \dfrac{0.9}{0.1} = 9$
$\Delta I_C = \beta\,\Delta I_B = 9 \times 0.4 = 3.6$ mA
So the answer is (a) 3.6 mA.
