What indicates continuity across a wire?

Continuity across a wire is indicated by the presence of a continuous electrical path, where the resistance is low and consistent along its length. A continuity test, often performed with a multimeter, will show a near-zero reading if the wire is intact. Conversely, a high resistance or infinite reading suggests a break or fault in the wire. Additionally, visual inspection for physical damage or corrosion can also indicate continuity issues.
