  1. Question 1

    Q1. A common-emitter amplifier has a current gain of 50. If the base current is changed by 10 μA, what is the change in collector current?

    • A) 0.5 mA
    • B) 1 mA
    • C) 0.1 mA
    • D) 5 mA

    Answer: 0.5 mA

    Explanation: Change in collector current = current gain * change in base current = 50 * 10 μA = 0.5 mA.
