  1. Question 1

    Q1. A superconducting wire and an insulating rod are similarly stressed. What is their primary conducting mechanism?

    • A) Both have free electrons
    • B) Superconductor has mobile ions
    • C) Insulator has mobile electrons
    • D) Superconductor has zero resistance

    Answer: Superconductor has zero resistance

    Explanation: Superconductors exhibit zero resistance. Insulators block current regardless of charge carriers.
