Which tool is essential for measuring voltage in electrical systems?

A multimeter is essential for measuring voltage in electrical systems because it is specifically designed to measure various electrical parameters, including voltage, current, and resistance. When measuring voltage, the multimeter can be set to the appropriate range to ensure accurate readings of both AC (alternating current) and DC (direct current) voltage.

The versatility of the multimeter makes it a fundamental tool in electrical diagnostics and troubleshooting. Its ability to switch between different functions allows technicians to quickly check voltage levels, which is crucial for ensuring that electrical circuits are functioning correctly and safely.

While other tools like a clamp meter can measure current and a current probe assists in current measurement, they do not provide the capability to directly measure voltage. Wire strippers, on the other hand, are used for preparing wires for connections but do not measure any electrical parameters. The precise function of a multimeter establishes its importance in electrical measurement tasks.
