Vedclass · Answer

(A) The current gain $\beta$ in a common emitter configuration is defined as the ratio of the change in collector current $\Delta I_C$ to the change in base current $\Delta I_B$.Formula: $\beta = \frac{\Delta I_C}{\Delta I_B}$Given: $\beta = 80$ and $\Delta I_B = 250 \ \mu A$.To find the change in collector current $\Delta I_C$,we rearrange the formula:$\Delta I_C = \beta 	imes \Delta I_B$$\Delta I_C = 80 	imes 250 \ \mu A$Therefore,the change in collector current is $80 	imes 250 \ \mu A$.

In a common emitter transistor,the current gain is $80$. What is the change in collector current,when the change in base current is $250 \ \mu A$?
