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