Continuity is the property of a circuit that allows current to flow through it. A multimeter is a device that can be used to measure continuity. To read continuity on a multimeter, you will need to set the multimeter to the continuity setting. This setting is usually indicated by a symbol that looks like a sound wave. Once the multimeter is set to the continuity setting, you will need to touch the probes of the multimeter to the two points in the circuit that you want to test. If there is continuity between the two points, the multimeter will beep.
Continuity is important because it can be used to troubleshoot electrical circuits. If a circuit is not working, you can use a multimeter to test the continuity of the circuit to see if there is a break in the circuit. Continuity can also be used to test the continuity of wires and cables.
