What does a multimeter measure?

A multimeter is a versatile instrument designed to measure multiple electrical parameters, making it an essential tool for electricians and technicians. The correct choice highlights its ability to measure voltage, current, and resistance, encompassing the three fundamental electrical properties needed for diagnosing and troubleshooting circuits.

Voltage measurement allows the user to determine the electric potential difference between two points, which is crucial for evaluating power supply levels. Current measurement provides insights into the flow of electrical charge within a circuit, helping to identify overloads or short circuits. Resistance measurement is important for assessing the integrity of components and connections, determining if they are functioning as intended or if there is a break in continuity.

By measuring all three parameters, a multimeter serves a wide range of applications, from simple household checks to complex diagnostic tasks in various electrical systems. This multifunctionality ensures that technicians have a comprehensive understanding of the electrical conditions they are working with.
