  1. Question 1

    Q1. Why does a three-phase AC generator produce three separate outputs with 120° phase shifts?

    • A) Minimize harmonic distortion
    • B) Balance rotating magnetic field
    • C) Maximize power factor
    • D) Simplify rectification process

    Answer: Balance rotating magnetic field

    Explanation: Three-phase ensures continuous power delivery. Option A is a secondary benefit of balanced systems.
