Q77MHT CET 2020 · 19 OCT · SHIFT 2Easy

Junction Transistor

A transistor having $\alpha = 0.8$ is connected in common emitter configuration. When the base current changes by 6 mA, then the change in collector current is

Show answer and solution

Answer: (b)

$\beta = \frac{\alpha}{1-\alpha} = \frac{0.8}{0.2} = 4$
$\Delta I_C = \beta\,\Delta I_B = 4 \times 6 = 24$ mA
So the answer is (b) 24 mA.
