To solve the problem step by step, we will use the relationships between the emitter current (I_E), collector current (I_C), base current (I_B), and the transistor parameters alpha (α) and beta (β). ### Step 1: Calculate the Collector Current (I_C) We know that: \[ \alpha = \frac{I_C}{I_E} \] From this, we can rearrange the formula to find the collector current: ...
