A multimeter can measure which of the following?

A multimeter is a versatile instrument used in electrical testing and troubleshooting, capable of measuring various electrical parameters. The correct choice indicates that a multimeter can measure voltage, current, and resistance, which are the three fundamental electrical characteristics.

When measuring voltage, a multimeter can determine the electrical potential difference between two points in a circuit, which is essential for diagnosing circuits and ensuring they operate within specified conditions. Measuring current allows users to assess the flow of electric charge, which is crucial for understanding how much electricity is being consumed or flowing through a circuit. Lastly, measuring resistance helps identify issues with components by determining whether they are intact or failing, as a change in resistance can indicate problems such as shorts or open circuits.

The other options imply that a multimeter is limited in its capabilities to only two of these measurements at a time, which does not reflect the instrument's comprehensive functionality. This versatility makes the multimeter an invaluable tool for both professionals and amateurs working with electrical systems.
