(A) Given:Change in collector current, $\Delta I_c = 8.2 \,mA$Change in emitter current, $\Delta I_e = 8.3 \,mA$We know that the emitter current is the sum of base current and collector current: $\Delta I_e = \Delta I_b + \Delta I_c$Therefore, the change in base current is: $\Delta I_b = \Delta I_e - \Delta I_c = 8.3 \,mA - 8.2 \,mA = 0.1 \,mA$The forward current ratio (current gain $\beta$) is defined as the ratio of the change in collector current to the change in base current:$\beta = \frac{\Delta I_c}{\Delta I_b} = \frac{8.2 \,mA}{0.1 \,mA} = 82$

While a collector to emitter voltage is constant in a transistor, the collector current changes by $8.2 \,mA$ when the emitter current changes by $8.3 \,mA$. The value of forward current ratio is
