  1. Question 1

    Q1. In a meter bridge, the balance point is at 40 cm. If the resistance in the left gap is 10 ohms, what is the resistance in the right gap?

    • A) 15 ohms
    • B) 20 ohms
    • C) 25 ohms
    • D) 30 ohms

    Answer: 15 ohms

    Explanation: R2 = R1 * (100 - l)/l = 10 * (100 - 40)/40 = 15 ohms.
