Junction Transistor

In common emitter configuration of transistor amplifier, $r_i, R_L$ and $\beta$ represent the input resistance, load resistance and the a.c. current gain respectively. The voltage gain $A_V$ and power gain $A_P$ are represented in magnitude respectively by

Show answer and solution

Answer: (c)

$A_V = \beta\frac{R_L}{r_i}$
$A_P = \beta A_V = \beta^2\frac{R_L}{r_i}$
So the answer is (c).
