What is the primary function of a multimeter in electrical testing?


✔✔A multimeter is used to measure voltage, current, and resistance in electrical circuits,

allowing electricians to check the status of a circuit and diagnose problems.




What does an ohmmeter measure?


✔✔An ohmmeter measures the resistance in an electrical circuit or component, helping to

identify whether a circuit is open, shorted, or functioning properly.




What is the purpose of a clamp meter?


✔✔A clamp meter is used to measure the current flowing through a conductor without having to

disconnect the circuit, providing a quick and safe way to check current.




Why is it important to test continuity in an electrical circuit?


✔✔Testing continuity ensures that electrical paths are intact and that there are no breaks or open

circuits, which could cause the system to malfunction.

, How is a voltage tester used in electrical work?


✔✔A voltage tester is used to determine whether voltage is present in a circuit, helping

electricians verify whether a circuit is live or de-energized before working on it.




What is the function of a ground resistance tester?


✔✔A ground resistance tester measures the resistance of a grounding system, ensuring that the

electrical system is properly grounded for safety.




What is the difference between an analog and a digital multimeter?


✔✔An analog multimeter uses a moving needle to display readings, while a digital multimeter

shows readings in numeric form on a digital display, providing more precise results.




What does a loop tester measure in an electrical system?


✔✔A loop tester measures the impedance of a circuit loop to ensure the system provides a safe

and effective path for current to flow, especially in protective earth systems.
