What is a continuity test used for?

• A. To check ground fault current.
• B. To test arc flash risk.
• C. To measure insulation resistance.
• D. To verify there is a complete electrical path between two points.

Answer: (D)

A continuity test checks whether there is a continuous conducting path between two points in an electrical circuit. Using a low‑voltage tester or a multimeter with a continuity function, a complete path typically produces a beep or shows very low resistance. This confirms that wiring, connections, switches, and terminations are intact so current can flow where it’s supposed to. If the test shows high or infinite resistance, the path is open and something in the circuit is faulted. This is exactly what verifying a complete electrical path between two points means. It’s not used to assess ground fault current, arc flash risk, or insulation resistance, which involve different tests and purposes.
