In common emitter amplifier, the current gain is 62. The collector resistance and input resistance are 5kΩ an 500Ω respectively. If the input voltage is 0.01 V, the output voltage is |
0.62 V 6.2 V 62 V 620 V |
6.2 V |
$\frac{V_0}{V_{in}}=\frac{R_0}{R_{in}}×β=\frac{5×10^3×62}{500}=10×60=620$ $V_0=620×V_{in}=620×0.01=6.2V$ $∴V_0=6.2volt$ |
