ohm (Ω)
The derived unit of electrical resistance, in the case of direct current, or impedance, in the case of alternating current, in the SI system of units. 1 ohm (Ω) is the resistance that produces a potential difference of one volt when a current of one ampere is flowing through it. It is named after the German physicist Georg Ohm (1789-1854).
