Answer:
OFF
Step-by-step explanation:
When testing for continuity in an electrical circuit, the circuit being tested should be off. Continuity testing is used to check if there is an uninterrupted path for electrical current flow between two points in a circuit. It's typically done to identify open circuits (breaks or interruptions in the wiring) or to ensure that a switch, fuse, or component is functioning properly.
Here's how continuity testing is generally conducted:
Ensure that the circuit or component you are testing is de-energized and turned off. This means that no electrical power should be applied to the circuit during the test to prevent electrical hazards.
Use a continuity tester or a multimeter set to the continuity (or "beep") mode. This mode is designed for continuity testing and will produce an audible tone or light up when continuity is detected.
Touch the probes of the continuity tester or multimeter to the two points in the circuit that you want to test for continuity. For example, you might be checking if a wire is continuous from one end to the other or if a switch is closed when it should be.
If the circuit is continuous (there is a complete path for electrical current), the continuity tester will produce an audible beep or show a reading (e.g., close to zero ohms on the multimeter display).
Testing for continuity with the circuit turned on can be dangerous and is not recommended. It can lead to electrical shock, damage to the circuit, or even injury. Always ensure the circuit is de-energized and turned off before performing continuity testing to maintain safety.
