Question:

In a transistor amplifier, $β = 62$, $R_L = 5000 Ω$ and internal resistance of the transistor is 500 . The voltage amplification of the amplifier will be:

Options:

500

620

780

950

Correct Answer:

620

Explanation:

Voltage amplification = $\frac{βR_L}{R_e}=\frac{62×5000}{500}=620$
