What is the primary use of multimeters in electrical work?

Multimeters are versatile tools commonly used in electrical work because they can perform multiple functions essential for diagnosing and troubleshooting electrical systems. The primary uses of a multimeter include measuring voltage, current, and resistance.

When measuring voltage, a multimeter can evaluate the electrical potential difference between two points in a circuit, which is crucial for ensuring that circuits are functioning correctly. In terms of current, the multimeter can determine the flow of electrical charge in a circuit, helping technicians assess whether devices are drawing the appropriate amount of power. Resistance measurement is also vital, as it helps in checking components and circuits for continuity and overall functionality.

The ability to perform all these measurements effectively makes multimeters a fundamental instrument in electrical work, facilitating a comprehensive understanding of the electrical parameters in a system. This multifunctionality is why the correct answer encompasses all these capabilities of a multimeter.
