Question

In a common emitter transistor amplifier $\beta$ $=60$, $R_0$ $=5000$$\Omega$ and internal resistance of a transistor is $500$$\Omega$. The voltage amplification of amplifier will be

• A. $500$
• B. $460$
• C. $600$
• D. $560$

Answer 1

Answer: (C)

$600$

Voltage amplification, $A_v=\beta \frac{R_0}{R_i}=60\times \frac{5000}{500}=600$
