Vedclass · Answer

(B) Given: Current gain $(\beta)$ = $62$, Collector resistance $(R_C)$ = $5 	ext{ k}\Omega = 5000 	ext{ }\Omega$, Input resistance $(R_i)$ = $500 	ext{ }\Omega$, Input voltage $(V_i)$ = $0.01 	ext{ V}$.First, calculate the voltage gain $(A_v)$ of the amplifier:$A_v = \beta 	imes \frac{R_C}{R_i} = 62 	imes \frac{5000}{500} = 62 	imes 10 = 620$.The output voltage $(V_o)$ is given by the product of voltage gain and input voltage:$V_o = A_v 	imes V_i = 620 	imes 0.01 	ext{ V} = 6.2 	ext{ V}$.Therefore, the correct option is $B$.

In a common emitter amplifier configuration, the current gain is $62$. The collector resistance and input resistance are $5 \text{ k}\Omega$ and $500 \text{ }\Omega$ respectively. If the input voltage is $0.01 \text{ V}$, the output voltage will be (in $V$)
