  1. Question 1

    Q1. An electrician must check whether a household fuse path is broken without calculating resistance from scratch on paper. Which meter is most directly used to test continuity or resistance in a circuit?

    • A) An ammeter is inserted in series to measure current
    • B) A voltmeter is placed across components to measure voltage
    • C) An ohmmeter measures electrical resistance of a path
    • D) A wattmeter measures electric power drawn by a load

    Answer: An ohmmeter measures electrical resistance of a path

    Explanation: An ohmmeter applies a small known voltage across a circuit path and measures the resulting current, then displays the calculated resistance; it is the standard tool for testing whether a fuse, wire, or component is intact or open-circuit.
