To fully answer this question, we need to know the value of the transistor's current gain, also known as the beta (β) value. The β value determines the ratio of collector current (IC) to base current (IB) in a common-emitter (CE) transistor configuration.
Let's assume the β value of the transistor is 50. This means that for every 1 unit of base current, we get 50 units of collector current. Therefore, if the base current (IB) is 25 μA (microamps), the collector current (IC) would be:
IC = β * IB
IC = 50 * (25 μA)
IC = 1250 μA or 1.25 mA
So, with a base current of 25 μA, the collector current of the CE transistor amplifier would be 1.25 mA.
