Continuity testing is a simple electrical test used to verify if an electrical circuit is complete, meaning that current can flow through it without interruption. It is commonly used to test wires, cables, and other electrical components to ensure they are functioning properly. Continuity testing can be performed using a variety of tools, including a multimeter, a continuity tester, or even a simple battery and light bulb.
Continuity testing is an important part of electrical troubleshooting, as it can help to identify breaks or faults in a circuit. It can also be used to verify that a new circuit is properly wired before it is energized. In some cases, continuity testing can also be used to identify specific components in a circuit, such as resistors, capacitors, and diodes.
