Which device is utilized to check for electrical continuity?

The correct choice is the device used to check for electrical continuity, which is an ohmmeter. An ohmmeter is designed to measure resistance in electrical circuits, and it effectively indicates whether there is a continuous path for current to flow. This is critical in troubleshooting electrical circuits, as a lack of continuity often points to a break or fault in the circuit that needs to be addressed.

When you connect an ohmmeter across two points in a circuit, it measures the resistance between those points. A reading of zero or near zero ohms suggests a good connection, indicating that continuity is present. Conversely, a high reading or infinite resistance signifies a break in the connection, confirming that there is no continuity.

Other devices like voltmeters and ammeters serve different purposes. A voltmeter measures the electrical potential difference between two points in a circuit, while an ammeter measures the flow of electric current. Both do not assess continuity directly. A thermometer is entirely unrelated, as it measures temperature, not electrical properties.
