What measurement is used to determine the continuity of a circuit?

Continuity in a circuit is a measure of whether an electric path is uninterrupted, allowing current to flow. The most common way to determine continuity is through the use of a continuity tester or a multimeter set to the continuity setting. When the circuit is complete, the device emits a tone or indicates a low resistance reading, confirming that current can flow without interruption.

While voltage, resistance, and conductivity relate to different aspects of electrical systems, they do not specifically measure continuity. Voltage indicates the potential difference in a circuit, resistance measures how much a component opposes the flow of electric current, and conductivity pertains to how easily electricity flows through a material. Continuity, executed with the dedicated method, gives a direct indication of the circuit's operational state.
