What does a multimeter measure?

A multimeter is a versatile tool designed to measure multiple electrical properties within a circuit, specifically voltage, current, and resistance. This capability allows users to troubleshoot and analyze circuits more comprehensively than tools limited to measuring just one parameter.

When set to measure voltage, the multimeter can determine the potential difference between two points. In current measurement mode, it can assess the flow of electric charge through the circuit. For resistance, it checks how much the circuit opposes the flow of electric current.

This multi-functionality is crucial for electricians and technicians, as it reduces the need for multiple devices and improves efficiency. Other options that suggest limiting measurements to voltage, current, or resistance alone do not reflect the true flexibility and capability of a multimeter.
