How can you test for continuity in an electrical circuit?

To test for continuity in an electrical circuit, using a multimeter set to the continuity setting is the most effective method. This function will allow the multimeter to send a small current through the circuit. If the circuit is continuous and there are no breaks, the multimeter will indicate this by beeping or displaying a low resistance value. The continuity setting is specifically designed for this purpose, making it a reliable choice for determining whether a circuit path is complete.

Other methods listed have limitations; for instance, an ammeter measures current flow, which would not be useful without first confirming circuit continuity. A visual inspection, while helpful for identifying obvious issues like damaged wires, may not detect all problems affecting continuity. Measuring voltage with a voltmeter can indicate the presence of voltage in a circuit but does not confirm that the circuit path is intact, as it does not measure the resistance or flow of current needed to determine continuity.
