What kind of equipment is used for measuring voltage?

A voltmeter is specifically designed to measure voltage in an electrical circuit. It is connected in parallel to the component where the voltage needs to be measured, allowing it to accurately read the electrical potential difference between two points. This function is essential in both diagnostics and verifying that systems are operating within their designated voltage ranges.

While other instruments such as a multimeter can also measure voltage, they have multiple functions which may include measuring current and resistance. The voltmeter’s primary focus on voltage measurement makes it the most straightforward and dedicated tool for that specific task.

An ampermeter is used to measure current, while an ohmmeter measures resistance. These tools serve distinct purposes and are not suitable for measuring voltage, which is why they do not apply in this context.
