Vedclass · Answer

(C) In a common base $(CB)$ configuration,the current gain $\alpha$ is defined as the ratio of the change in collector current $(\Delta I_C)$ to the change in emitter current $(\Delta I_E)$.$\alpha = \frac{\Delta I_C}{\Delta I_E}$Given:$\alpha = 0.98$$\Delta I_E = 5.00 \,mA$To find the change in collector current $(\Delta I_C)$:$\Delta I_C = \alpha 	imes \Delta I_E$$\Delta I_C = 0.98 	imes 5.00 \,mA$$\Delta I_C = 4.90 \,mA$Therefore,the change in collector current is $4.9 \,mA$.

In a common base transistor circuit,the current gain is $0.98$. On changing emitter current by $5.00 \,mA$,the change in collector current is ......... $mA$.
