MDCAT Physics MCQ #101

  1. Question 1

    Q1. Why does a three-phase motor rotate without a starter capacitor?

    • A) Magnetic field rotates automatically
    • B) Phases create rotating field
    • C) Stator windings self-induct
    • D) Rotor induces its own current

    Answer: Phases create rotating field

    Explanation: Three-phase supply generates rotating magnetic field inherently. Option A is vague about field generation.
