Question

What is the voltage gain in a common emitter amplifier, where input resistance is $3 \,\Omega$ and load resistance $24\,\Omega \, \beta = 0.6$?

• A. 8.4
• B. 4.8
• C. 2.4
• D. 480

Answer 1

Answer: (B)

4.8

Answer 2

Voltage gain, $A_{v}=\beta \frac{R_{L}}{R_{i}}$
$=0.6 \times \frac{24}{3}=4.8$
