What tool is commonly used to measure circuit continuity?

A multimeter is a versatile tool commonly used to measure various electrical parameters, one of which is circuit continuity. It works by sending a small current through the circuit being tested; if the circuit is continuous, this current will flow, and the multimeter will provide a reading, often accompanied by an audible beep or light indicator. This allows electricians to quickly determine whether electrical connections are intact and can help identify faults in wiring, switches, and other components.

In contrast, a clamp meter primarily measures current without requiring a direct connection to the circuit, making it less suitable for testing continuity. A voltage tester is designed specifically to check for voltage presence rather than continuity. A circuit tracer is useful for locating wiring paths and ensuring that circuits are intact, but it does not measure continuity in the same direct manner as a multimeter. Therefore, the multimeter is the most appropriate tool for the task of measuring circuit continuity.
