Electrical continuity is the ability of an electrical circuit to conduct electricity. It is important to check electrical continuity to ensure that a circuit is working properly and that there are no breaks in the circuit. There are a few different ways to check electrical continuity, but the most common method is to use a multimeter.
A multimeter is a device that can measure electrical current, voltage, and resistance. To check electrical continuity, set the multimeter to the ohms setting and then touch the probes of the multimeter to the two terminals of the circuit. If the multimeter reads a low resistance, then the circuit is continuous. If the multimeter reads a high resistance, then there is a break in the circuit.
