A ________ is used to check for continuity:

A device used to check for continuity is an ohmmeter. Continuity testing is important in electrical systems to determine if there is a complete path for current flow. An ohmmeter works by measuring the resistance in a circuit; if the resistance is low or near zero, this indicates that continuity exists, meaning electricity can flow through the circuit without interruption. This is particularly useful for troubleshooting electrical components, wires, and connections to ensure they are functioning correctly.

While a voltmeter measures voltage, an ammeter measures current, and a multimeter can perform multiple functions including measuring voltage, current, and resistance, it is the ohmmeter that is specifically designed for checking continuity by assessing the resistance in a given path.
