If a continuity test shows a good path, what is true?

• A. It has zero resistance
• B. It is perfectly insulated
• C. It will conduct current
• D. It cannot withstand any current

Answer: (C)

A continuity test checks whether there is a complete, unbroken conductive path between two points. When it shows a good path, it means there is a continuous conductor linking those points so that current can flow when a source is applied. This doesn’t require zero resistance—real conductors have some finite resistance, and continuity testers look for a low enough resistance to indicate a complete path. It also isn’t saying the path is perfectly insulated; on the contrary, it must be conductive to carry current. And it doesn’t imply the path can’t carry current at all; once a source is connected, current will flow through that path according to Ohm’s law, within the conductor’s rating. So the statement that matches a good continuity path is that it will conduct current.
