What does a multimeter measure?

A multimeter is a versatile instrument used in electronics to measure various electrical parameters. The correct answer highlights that a multimeter can measure voltage, current, and resistance, which are fundamental electrical properties in circuits.

Voltage measurement allows the user to assess the potential difference between two points in a circuit, which is crucial for diagnosing voltage levels and ensuring components are operating within their specified range. Current measurement enables the evaluation of the flow of electric charge, which is important for understanding how much electricity is being used by a component or circuit. Resistance measurement provides insight into how much a component opposes the flow of current, which is helpful for identifying faulty components or assessing the integrity of connections in a circuit.

While there are specialized multimeters that can also measure other parameters like capacitance and temperature, the standard digital multimeter is primarily designed to measure voltage, current, and resistance. This versatility makes the multimeter an essential tool for engineers and technicians in troubleshooting and designing electronic circuits. Other options, which mention additional parameters like capacitance or temperature, do not represent the basic functionalities of most traditional multimeters.
