ohmmeter
Electrical resistance gauge
An ohmmeter is an instrument for measuring electrical resistance, calibrated in ohms.
It works by passing a small current through a circuit and measuring the voltage drop.
Modern digital multimeters typically include ohmmeter functions alongside voltage and current measurement.
