ohm 
"unit of electrical resistance," 1867, in allusion to Ger. physicist Georg S. Ohm (1789-1854), who determined the law of the flow of electricity. Originally proposed as ohma (1861) as a unit of voltage.

Function: noun
: the practical mks unit of electrical resistance equal to the resistance of a circuit in which a potentialdifference of one volt produces a current of one ampere —ohm·ic /'O-mik/ adjective
Ohm, Georg Simon (1789–1854), Germanphysicist. Ohm is best remembered for his discovery of a law of electricity that is now called Ohm's law in his honor. He summarized his discovery in a pamphlet published in 1827. His work exertedgreat influence on the theory and applications of current electricity. The physical unit measuring electrical resistance was officially designated the ohm by the Paris Electrical Congress of1881.
