MDCAT Physics MCQ #491

  1. Question 1

    Q1. What is the purpose of a shunt in an ammeter?

    • A) To increase the resistance of the circuit
    • B) To decrease the sensitivity of the ammeter
    • C) To allow measurement of larger currents
    • D) To measure voltage

    Answer: To allow measurement of larger currents

    Explanation: A shunt diverts excess current around the ammeter, allowing measurement of larger currents. Option A is incorrect as shunts actually decrease the total resistance.
