When performing continuity testing of twisted pair cable, the electrical quantity measured is _____.

• A. Capacitance
• B. Inductance
• C. Resistance
• D. Impedance

Answer: (C)

Continuity testing is about confirming a complete electrical path. When you measure with a meter set to resistance, you’re checking how much opposition there is to a small DC current flowing from one end of a conductor to the other. For a twisted pair that’s intact, the path is continuous, so the resistance is a small, finite value that reflects the length of the wire. If there’s a break, the path is open and the resistance appears very high or effectively infinite. That’s why resistance is the measured quantity in continuity testing. Capacitance, inductance, and impedance describe how a component or circuit behaves with AC signals or in terms of energy storage and reactive effects, not whether a DC path exists.
