  • In a common-emitter amplifier, the load resistance of the output circuit is times the resistance of the input circuit.

In a common-emitter amplifier, the load resistance of the output circuit is 1000 times the resistance of the input circuit. If \alpha = 0.98, then voltage gain is

Option: 1

49\times 10^{3}


Option: 2

2.5\times 10^{2}


Option: 3

1.5\times 10^{2}


Option: 4

4.9

\mathrm{Given,\ \quad \beta=\frac{\alpha}{1-\alpha}=\frac{0.98}{1-0.98}=49}\\ \mathrm{\therefore \quad Voltage\ gain\ =\beta \frac{R_2}{R_1}=49 \times 1000=49 \times 10^3}
