  1. Question 1

    Q1. A wire of resistance 8 ohm is bent to form a circle. The resistance between two diametrically opposite points is

    • A) 2 ohm
    • B) 4 ohm
    • C) 8 ohm
    • D) 1 ohm

    Answer: 2 ohm

    Explanation: The resistance between two diametrically opposite points is R / 4, hence 8 / 4 = 2 ohm, as the wire is divided into 4 equal parts in parallel
