What does a multimeter measure?

A multimeter is a versatile instrument designed to measure multiple electrical parameters, including voltage, current, and resistance. This capability makes it an essential tool in electrical work, as it allows technicians and engineers to diagnose and troubleshoot electrical circuits effectively.

When measuring voltage, a multimeter can determine the potential difference between two points in a circuit, which is crucial for understanding how much electrical energy is available. For measuring current, the multimeter can indicate the flow of electric charge through a circuit, which helps in assessing the performance and safety of electrical components. Additionally, it can measure resistance, which indicates how much a material opposes the flow of electric current, aiding in identifying faulty components or connections within a circuit.

The integrated functionality of a multimeter, combining these three measurements, allows it to be a comprehensive diagnostic tool. This is why the answer indicating that a multimeter measures voltage, current, and resistance is correct.
