A continuity tester is a device which tests the continuity of the wire at hand. It is an indispensable tool to check broken wires and undesired shorting of wires. If we want to check if the wire is connected from one end to another, then use the probes of the continuity tester and put to the ends of the wires to be tested. If the wires are connected, then the circuit makes a sound indicating that the wires is continuous without any break in the middle. We can also make use of this tool to make a tester to check discontinuity of wires. Get detailed information about this circuit in the post: Simple Continuity Tester Circuit.
