Vedclass · Answer

(A) Given: Current gain $\beta = 49$,Change in base current $\Delta I_B = 5.0 \ \mu A$.The change in collector current is given by $\Delta I_C = \beta 	imes \Delta I_B$.Substituting the values: $\Delta I_C = 49 	imes 5.0 \ \mu A = 245 \ \mu A$.The change in emitter current is given by $\Delta I_E = \Delta I_B + \Delta I_C$.Substituting the values: $\Delta I_E = 5.0 \ \mu A + 245 \ \mu A = 250 \ \mu A$.Therefore,the change in collector current is $245 \ \mu A$ and the change in emitter current is $250 \ \mu A$.

In a common-emitter transistor,the current gain $\beta$ is $49$. If there is a change of $5.0 \ \mu A$ in the base current,what will be the change in the collector current and the emitter current?
