Which device checks for the existence of a complete electrical system between two points?

• A. Troubleshooting Charts
• B. Troubleshooting Process Step
• C. Check for the Obvious
• D. Continuity Check/Test

Answer: (D)

A continuity check/test is used to confirm that there is a complete electrical path between two points. By using a continuity tester or a multimeter in continuity or low-resistance mode, you verify that current can flow from one point to the other. When the path is complete, the meter usually shows near-zero resistance and may emit a beep. If the path isn’t complete, you’ll see high or infinite resistance, indicating an open circuit. This checks wiring integrity and connections to ensure the circuit is truly continuous, which is different from troubleshooting charts, process steps, or general checks that don’t verify the physical path of the electrical system.
