Which tool is specifically designed to measure voltage?

The voltmeter is specifically designed to measure voltage in an electrical circuit. It operates by being connected in parallel with the component whose voltage is to be measured, allowing it to capture the potential difference between two points. When connected properly, the voltmeter provides a readout of the voltage level, which is essential for diagnosing electrical problems, ensuring proper circuit operation, and conducting safety checks.

In contrast, other tools serve different purposes: an ammeter measures current, an ohmmeter measures resistance, and a clamp meter can measure current without direct contact with the wire but does not measure voltage directly. Correctly identifying the specific function of the voltmeter helps in selecting the right tool for electrical measurements, ensuring accurate readings and effective troubleshooting in various applications.
