  1. Question 1

    Q1. A conductor has a resistivity of 1.8 × 10⁻⁸Ωm. What is its resistivity at 0°C?

    • A) 1.8 × 10⁻⁸Ωm
    • B) 1.8 × 10⁻⁵Ωm
    • C) 1.8 × 10⁻¹⁰Ωm
    • D) 1.8 × 10⁻¹⁵Ωm

    Answer: 1.8 × 10⁻¹⁰Ωm

    Explanation: Resistivity decreases with increasing temperature, so 0°C has lower resistivity.
