MDCAT Physics MCQ #497

  1. Question 1

    Q1. When is the Wheatstone bridge most sensitive?

    • A) When all resistances are very high
    • B) When all resistances are very low
    • C) When all four resistances are equal
    • D) When the ratio arms are equal

    Answer: When all four resistances are equal

    Explanation: The Wheatstone bridge is most sensitive when all four resistances are equal, balancing the bridge. Option A is incorrect as high resistances don't necessarily increase sensitivity.
