What does a multimeter measure?

A multimeter is a versatile instrument used to measure multiple electrical properties, making it a critical tool for anyone working in the electrical field. It can measure voltage in both AC and DC circuits, allowing users to assess the electrical potential difference between two points. Additionally, it measures current, allowing for the assessment of the flow of electric charge through a circuit. Resistance measurement is also a key feature, enabling users to determine how much a component resists the flow of current, which is essential for diagnosing circuit issues or checking component health.

The ability to measure all three of these key characteristics—voltage, current, and resistance—gives the multimeter its multifunctional nature. This capability distinguishes it from other options that may focus on just one aspect of electrical measurements. For instance, some tools may only measure resistance or voltage, but the multimeter’s breadth of functions makes it an indispensable tool for troubleshooting and ensuring the proper operation of electrical systems.
