Question

What is the voltage gain in a common emitter amplifier, where input resistance is 3 $\Omega$ and load resistance 24 $\Omega$ and $\beta = 61$?

• A. $8.4$
• B. 488
• C. 240
• D. 0

Answer 1

Answer: (B)

488

Answer 2

: Voltage gain

$A_{V} = \beta\frac{R_{o}}{R_{i}} = \frac{61 \times 24}{3} = 488$
