  1. Question 1

    Q1. How does the skin effect in AC conductors influence current distribution?

    • A) Current flows only on the surface at high frequencies.
    • B) It increases the effective cross-sectional area.
    • C) It reduces the resistivity of the conductor.
    • D) Current is uniformly distributed at all frequencies.

    Answer: Current flows only on the surface at high frequencies.

    Explanation: Skin effect concentrates current at high frequencies. D is incorrect because distribution is non-uniform.
