  1. Question 1

    Q1. Why does a step-down transformer have more turns in the primary coil?

    • A) Conserve magnetic flux
    • B) Reduce core losses
    • C) Follow voltage-turns ratio
    • D) Prevent insulation breakdown

    Answer: Follow voltage-turns ratio

    Explanation: N₁/N₂ = V₁/V₂ by Faraday's law. Option A describes magnetic circuit design principles but not the reason for turn ratios.
