Continuity testing is a fundamental procedure in electrical troubleshooting. It involves checking whether an electrical circuit is complete, meaning there is a continuous path for current to flow. A simple way to perform a continuity test is using a multimeter, a common tool that measures electrical properties. By placing the multimeter probes on different points in the circuit, you can determine if there is a complete path for current, indicated by a low resistance reading or an audible signal on the multimeter.
Checking continuity is essential in various electrical applications, including:
