In the experiment which we have just performed impedance is fifty times as important a factor as ohmic resistance.
It is impossible to overcome it entirely, but merely in part, for the ohmic resistance cannot be overcome.
unit of electrical resistance, 1867, in recognition of German 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. Related: ohmage; ohmic; ohmeter.
A unit of electrical resistance equal to that of a conductor in which a current of one ampere is produced by a potential of one volt across its terminals.
The unit of electrical resistance, named after the nineteenth-century German physicist Georg Ohm.
