Which measurement on a meter is used to test the conductivity of a circuit?

In the context of testing the conductivity of a circuit, the measurement of continuity is integral. Continuity tests are performed using a multimeter set to the continuity function, which checks whether electric current can flow through a circuit without interruption. When continuity is present, it effectively confirms that the conductive path is intact, allowing current to flow, demonstrating that components such as wires, switches, and connectors are functioning properly and that there are no breaks in the circuit.

While resistance is also an important measurement related to electrical circuits, it quantifies how strongly a material opposes the flow of current, rather than directly confirming if a circuit is complete. Voltage measures the electric potential difference between two points, indicating how much energy is available to push current through a circuit, and current measures the flow of electric charge in the circuit. Ultimately, continuity is specifically focused on whether or not electric current can travel through the circuit, which aligns closely with the concept of circuit conductivity.
