  1. Question 1

    Q1. The current in a circuit is measured using an ammeter. To minimize the error, the ammeter should have

    • A) High resistance
    • B) Low resistance
    • C) Zero resistance
    • D) Infinite resistance

    Answer: Low resistance

    Explanation: An ideal ammeter has zero resistance, but practically, it should have low resistance to minimize the voltage drop across it.
