MDCAT Physics MCQ #1274

  1. Question 1

    Q1. In a common-emitter amplifier, the phase difference between the input and output voltage is

    • A) 0°
    • B) 90°
    • C) 180°
    • D) 270°

    Answer: 180°

    Explanation: Common-emitter amplifier inverts the signal, so phase difference is 180°. Option A is incorrect due to not considering inversion.
