In common emitter amplifier, the current gain is 62. The collector resistance and input resistance are \mathrm{5k\Omega } and  \mathrm{500\Omega } respectively. If the input voltage is 0.01 V, the output voltage is:

Option: 1

0.62 V


Option: 2

6.2 V


Option: 3

62 V


Option: 4

0.01 V

\mathrm{\begin{aligned} & \frac{V_0}{V_i}=\beta=\frac{R_0}{R_i}=\frac{62 \times 5 \times 10^3}{500}=620 \\ & \therefore \quad V_0=620 V_i=620 \times 0.01=620 \end{aligned}}
