Junction Transistor question from MHT CET 2026 (14 May, Shift 1)

Q3MHT CET 2026 · 14 MAY · SHIFT 1Easy

Junction Transistor

For a transistor, the current ratio $\alpha_{DC} = \frac{69}{70}$ . The current gain $\beta_{DC}$ is

Show answer and solution

Answer: (c)

$\beta = \dfrac{\alpha}{1 - \alpha}$
$\beta = \dfrac{69/70}{1/70} = 69$
So the answer is (c) 69.
