Origin of ohm:
1861; after G. S. Ohm
Georg Simon, 1787–1854, German physicist.
a unit of electrical resistance equal to the resistance between two points on a conductor when a potential difference of one volt between them produces a current of one ampere
Ohm, Georg Simon Ohm(noun)
German physicist who formulated Ohm's law (1787-1854)
In the International System of Units, the derived unit of electrical resistance; the electrical resistance of a device across which a potential difference of one volt causes a current of one ampere. Symbol: u03A9
Origin: Named after the German physicist Georg Ohm.
The ohm is the SI derived unit of electrical resistance, named after German physicist Georg Simon Ohm. Although several empirically derived standard units for expressing electrical resistance were developed in connection with early telegraphy practice, the British Association for the Advancement of Science proposed a unit derived from existing units of mass, length and time and of a convenient size for practical work as early as 1861. The definition of the "ohm" unit was revised several times. Today the value of the ohm is expressed in terms of the quantum Hall effect.
