In common emitter amplifier, the current gain is 62. The collector resistance and input resistance are
\mathrm{5k\Omega } an \mathrm{500k\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

6.20 V

\mathrm{ \begin{aligned} & \frac{\mathrm{V}_0}{\mathrm{~V}_{\mathrm{i}}}=\frac{\mathrm{R}_0}{\mathrm{R}_{\mathrm{in}}} \times \beta=\frac{5 \times 10^3 \times 62}{300}=10 \times 62=620 \\ & \mathrm{~V}_0=620 \times \mathrm{V}_{\mathrm{in}}=620 \times 0.01=6.2 \mathrm{~V} \\ & \therefore \quad \mathrm{V}_0=6.2 \mathrm{volt} \end{aligned} }
