ohm

[ohm]
noun
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

Origin:
1861; named after G. S. Ohm

ohmic [oh-mik] , adjective
