Physics - Semiconductors Question with Solution | TestHub

For a common emitter (CE) amplifier, the voltage gain ($A_v$) is related to the current gain ($\beta$), load resistance ($R_L$), and input resistance ($R_{in}$) by the formula:$A_v=\beta \times \frac{R_L}{R_{in}}$ Given: $\beta =50$, $R_{in}=2\text{ k}\Omega$, $R_L=10\text{ k}\Omega$.$A_v=50\times \frac{10\text{ k}\Omega }{2\text{ k}\Omega }=50\times 5=250$. The voltage gain of the amplifier is 250.
