ohmmeters
Electrical resistance gauges
Ohmmeters are instruments that measure electrical resistance in ohms.
The device passes a small current through a circuit or component and calculates resistance from the resulting voltage drop.
Most ohmmeters today are integrated into multimeters rather than existing as standalone tools: Set the multimeter to ohms and check the continuity.
