Vedclass · Answer

(A) Given: $\alpha = 0.9$ and change in base current $\Delta I_B = 0.4 	ext{ mA}$.First, we calculate the current gain $\beta$ for the $CE$ configuration using the relation: $\beta = \frac{\alpha}{1 - \alpha}$.Substituting the value of $\alpha$: $\beta = \frac{0.9}{1 - 0.9} = \frac{0.9}{0.1} = 9$.The relationship between collector current change $\Delta I_C$ and base current change $\Delta I_B$ is given by: $\Delta I_C = \beta 	imes \Delta I_B$.Substituting the values: $\Delta I_C = 9 	imes 0.4 	ext{ mA} = 3.6 	ext{ mA}$.Therefore, the change in collector current is $3.6 	ext{ mA}$.

If a transistor having $\alpha = 0.9$ is used in $CE$ configuration, then for a change of $0.4 \text{ mA}$ in base current, what will be the change in collector current (in $\text{ mA}$)?
