Physics - Semiconductors Question with Solution | TestHub

Given, load resistance $R_L=6.5\text{ k}\Omega$

Input resistance $R_{in}=1.3\text{ k}\Omega$

Current gain $\beta =78$

The voltage gain $A_v$ is given by the formula:

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

Substituting the given values:

$A_v=78\times \frac{6.5}{1.3}$

$A_v=78\times 5=390$

Answer: 390
