Continuity testing with a voltmeter is a method used to determine if an electrical path is complete and unbroken. It verifies that current can flow uninterrupted between two points in a circuit. For example, this technique can be applied to check if a fuse is intact or if a wire has a break within its insulation.
The ability to ascertain electrical continuity provides significant benefits in troubleshooting and diagnostics across various electrical systems. It allows for the rapid identification of faulty components or wiring, saving time and resources in maintenance and repair. Historically, specialized continuity testers were employed, but modern multimeters, including voltmeters, incorporate this functionality, expanding their utility.
