# ohm

[ohm] /oʊm/
noun
1.
the standard unit of electrical resistance in the International System of Units (SI), formally defined to be the electrical resistance between two points of a conductor when a constant potential difference applied between these points produces in this conductor a current of one ampere. The resistance in ohms is numerically equal to the magnitude of the potential difference. Symbol: Ω.

ohm in Science
 ohm   (ōm)    The SI derived unit used to measure the electrical resistance of a material or an electrical device. One ohm is equal to the resistance of a conductor through which a current of one ampere flows when a potential difference of one volt is applied to it.
 Ohm, Georg Simon 1789-1854.   German physicist who discovered the relationship between voltage, current, and resistance in an electrical circuit, now known as Ohm's law. The ohm unit of electrical resistance is named for him.
