Vedclass · Answer

(B) Given:Current gain $(\beta)$ = $62$Collector resistance $(R_C)$ = $5\,k\Omega = 5000\,\Omega$Input resistance $(R_{in})$ = $500\,\Omega$Input voltage $(V_{in})$ = $0.01\,V$The voltage gain $(A_v)$ of a common emitter amplifier is given by:$A_v = \beta 	imes \frac{R_C}{R_{in}}$$A_v = 62 	imes \frac{5000}{500} = 62 	imes 10 = 620$The output voltage $(V_o)$ is given by:$V_o = A_v 	imes V_{in}$$V_o = 620 	imes 0.01\,V = 6.2\,V$Therefore,the output voltage is $6.2\,V$.

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