ohm meter
Electrical resistance gauge
An ohm meter (also ohmmeter) is an instrument that measures electrical resistance in ohms.
It works by passing a small current through a circuit and calculating resistance from the voltage drop.
Most modern multimeters include ohm meter functionality alongside voltage and current measurement: Use the ohm meter to check if the fuse is blown.
