Physics - Semiconductors Question with Solution | TestHub

The voltage gain $A_v$ of a transistor amplifier is given by the formula:

$A_v=\beta \times \frac{R_L}{R_{in}}$

Given:
AC current gain $\beta =64$
Load resistance $R_L=5400\Omega$
Input resistance $R_{in}=540\Omega$

Substituting the given values:

$A_v=64\times \frac{5400}{540}$

$A_v=64\times 10$

$A_v=640$

Answer: $640$
