|ohm (ōm) Pronunciation Key
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.
The unit of electrical resistance, named after the nineteenth-century German physicist Georg Ohm.
