ohm
[ ohm ]
/ oʊm /
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 of ohm
First recorded in 1861; named after G. S.
