Plain-language definition
Plain-language definition
An unbroken electrical path through which current can flow.
Why it matters
Continuity testing quickly finds broken traces, blown fuses, and disconnected cables without powering the device.
Technical detail
A continuity test applies a small test signal and indicates whether resistance between two points is low enough to represent a connected path.
Examples
- A multimeter beep across a fuse indicates that its path is intact.
