What is measured by a multimeter?

A multimeter is a versatile instrument designed to measure multiple electrical properties, including voltage, current, and resistance. When measuring voltage, the multimeter can determine both AC and DC voltage levels, making it an essential tool for various applications in electronics and electrical engineering.

In addition to voltage, the multimeter can measure current, whether it is in series or parallel within a circuit. This capability allows users to assess how much current is flowing through a particular component or the entire circuit, providing critical information for diagnosing potential issues.

Lastly, ohm measurement is another fundamental feature of multimeters, where they measure resistance in ohms. This function helps in checking the integrity of components, such as confirming if a resistor is functioning correctly or if a wire is continuous.

In summary, a multimeter is capable of measuring voltage, current, and resistance all in one device, making it an indispensable tool for anyone working with electrical systems.
