What does a multimeter measure?

A multimeter is a versatile instrument commonly used in electrical work for measuring multiple electrical properties. The correct answer reflects that a multimeter can measure voltage, current, and resistance.

Voltage measurement enables electricians to determine the potential difference between two points in an electrical circuit, which is essential for troubleshooting and ensuring circuits operate within safe limits. Current measurement allows for checking the flow of electric charge through a conductor, helping to diagnose issues such as overloads or short circuits. Resistance measurement is crucial for understanding the opposition to current flow in a circuit, which can indicate whether components are functioning properly or if there are faults like short circuits.

In essence, the capability of a multimeter to provide measurements of these three key electrical parameters makes it an indispensable tool for electricians, enhancing their ability to analyze and diagnose a wide range of electrical systems and components effectively.
