What does a multimeter measure?

A multimeter is a versatile instrument used for electrical measurements, capable of measuring voltage, current, and resistance. This functionality makes it indispensable for electricians and technicians when diagnosing and troubleshooting electrical systems.

Measuring voltage involves checking the potential difference between two points in a circuit, which is critical for ensuring that devices receive the appropriate power level. Current measurement allows the user to assess the flow of electricity through a conductor, which is essential for evaluating circuit performance and safety. Resistance measurement helps in identifying issues such as shorts or breaks in the circuit by determining how easily electricity can pass through a component or conductor.

The other options mention measurements that although can be relevant in certain contexts, do not encompass the primary functions of a typical multimeter. For example, while frequency, inductance, and capacitance are important electrical parameters, they usually require specialized equipment to measure accurately and are not standard functions found in most multimeters. Thus, the capability to measure voltage, current, and resistance establishes a multimeter as an essential tool for effective electrical diagnostics and work.
