What tool is commonly used to measure electrical voltage?

The multimeter is a versatile tool specifically designed to measure various electrical parameters, including voltage, current, and resistance. When measuring voltage, a multimeter is connected in parallel with the circuit, allowing it to accurately read the voltage level present in the electrical system. Its functionality makes it essential for troubleshooting and diagnosing electrical problems in vehicles, as it can provide immediate feedback on the electrical condition of components.

Other tools listed, such as an ammeter, are limited to measuring current and are connected in series within a circuit, while a resistance meter primarily measures resistance in ohms and is not suitable for voltage measurement. A clamp meter can measure current without needing to disconnect circuits, but it generally does not measure voltage directly in the same manner as a multimeter. Thus, the multimeter stands out as the appropriate tool for measuring electrical voltage.
