What does a multimeter measure?

A multimeter is a versatile instrument used in electrical testing and troubleshooting, capable of measuring various electrical properties. The correct answer, which states that a multimeter measures voltage, current, and resistance, highlights its multifunctional nature.

To break this down:

• Voltage: A multimeter can measure both AC and DC voltage, providing essential information about the electrical potential difference between two points in a circuit.

• Current: It also measures electrical current, allowing users to detect how much electric flow is present in a circuit, which is critical for diagnosing operational issues.

• Resistance: Finally, a multimeter can measure resistance, which helps identify whether components like resistors are functioning properly or if there is continuity in a circuit.

This combination makes a multimeter an invaluable tool for electricians and technicians, as it enables them to perform a comprehensive analysis of electrical systems, ensuring that all three fundamental properties can be assessed accurately and efficiently.

Other options, which limit the multimeter's capabilities to measuring only one of these properties, do not reflect the extensive functionality that defines a standard multimeter.
