What does a multimeter measure?

A multimeter is a versatile electronic measuring instrument that can measure multiple electrical properties. The correct answer reflects its capability to assess voltage, current, and resistance—all essential for diagnosing and troubleshooting electrical circuits.

When measuring voltage, the multimeter can be set to different ranges to accommodate both AC (alternating current) and DC (direct current) voltages, providing important insights into the voltage levels present in a circuit.

For current measurement, the multimeter can be configured to measure both AC and DC current, allowing users to assess the flow of electricity through different loads in a circuit.

Additionally, a multimeter can measure resistance, which is crucial for evaluating components like resistors and ensuring that circuits are functioning correctly without openings or shorts.

This multifunctional ability makes the multimeter an invaluable tool in electrical work, as it allows technicians to perform multiple tasks with a single device, streamlining the troubleshooting process and increasing efficiency.
