Question

In a common emitter transistor amplifier $\beta = 60, \,R_o = 5000\, \Omega$ and internal resistance of a transistor is $500 \,\Omega$Voltage amplification. The voltage amplification of amplifier will be

• A. 500
• B. 460
• C. 600
• D. 560

Answer 1

Answer: (C)

600

Answer 2

Voltage amplification
$A_{ v} = \beta \frac{R_{o}}{R_{i}} = 60\times \frac{5000}{500} = 600$
