To solve the problem step by step, we will follow the concepts of transistor operation and the relationships between emitter current (I_E), base current (I_B), and collector current (I_C). ### Step 1: Understand the relationship between currents in a transistor In a transistor, the emitter current (I_E) is the sum of the base current (I_B) and the collector current (I_C). This can be expressed as: \[ I_E = I_B + I_C \] ### Step 2: Express the changes in currents When there is a change in the emitter current (ΔI_E) and collector current (ΔI_C), the change in base current (ΔI_B) can be expressed as: ...
