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

Q7MHT CET 2026 · 14 MAY · SHIFT 1Easy

Junction Transistor

$\beta, R_L$ and $r$ are the a.c. current gain, load resistance and the input resistance of a transistor respectively in common emitter configuration, the voltage gain and the power gain are respectively

Show answer and solution

Answer: (a)

$A_V = \frac{\Delta V_o}{\Delta V_i} = \frac{\beta\,\Delta I_B R_L}{\Delta I_B\, r} = \beta\frac{R_L}{r}$
$A_P = \beta \times A_V = \beta^2\frac{R_L}{r}$
So the answer is (a).
