  1. Question 1

    Q1. The resistance of a conductor is 10 ohm at 0°C. If the temperature coefficient is 0.004 /°C, its resistance at 100°C is?

    • A) 14 ohm
    • B) 10 ohm
    • C) 12 ohm
    • D) 16 ohm

    Answer: 14 ohm

    Explanation: R = R0(1 + αΔT) = 10(1 + 0.004*100) = 10(1 + 0.4) = 14 ohm.
