If a wire has continuity, it will have almost no resistance.

• A. It will have almost no resistance
• B. It will have high resistance
• C. It will have unpredictable resistance
• D. It will be a short circuit

Answer: (A)

Continuity means there is a complete conducting path between the two points you’re testing. A good wire provides that path with only a very small amount of resistance, so when you test for continuity, you’re typically measuring something close to zero ohms. That’s why the statement is true: if the wire has continuity, it’s capable of carrying current with negligible resistance along its length. Real wires do have some resistance—depends on material, length, and gauge—but in practical terms for a continuity check, that resistance is considered almost negligible compared to the rest of the circuit.

High resistance would mean the path isn’t continuous. Unpredictable resistance isn’t characteristic of a healthy, continuous wire. A short circuit refers to a path of very low resistance that bypasses the intended circuit components, which is a different condition than simply having a continuous wire.
