Scientific definitions for ohmmeter

ohmmeter

[ ōm′mē′tər ]

An instrument used for direct measurement of the electrical resistance of a material or electronic component, usually in ohms. Ohmmeters typically use an ammeter to measure current through the material after it has been given some set voltage by the ohmmeter; the direct-current resistance of the sample can then be directly determined through Ohm's law. Compare voltmeter.
