Siemens

 

the unit of electrical conductivity in the International System of Units (SI). Named in honor of W. von Siemens, the unit has the designation S in the international system. A Siemens is equal to the electrical conductivity of a conductor having a resistance of 1 ohm. In the 19th century, the Siemens was a unit of electrical resistance. Now obsolete, it was equal to the resistance of a column of mercury with a length of 1 m and a cross-sectional area of 1 mm2 at 0°C.

[′sē·mənz]
(electricity)
A unit of conductance, admittance, and susceptance, equal to the conductance between two points of a conductor such that a potential difference of 1 volt between these points produces a current of 1 ampere; the conductance of a conductor in siemens is the reciprocal of its resistance in ohms. Formerly known as mho (Ω); reciprocal ohm. Symbolized S.

Siemens

(Siemens AG, Munich, Germany, www.siemens.com) A leading European electrical and electronics firm founded in 1847. Siemens has more than 430,000 employees in nearly 200 countries, and more than 50,000 professionals are engaged in research and development. In 1990, the computer division of Siemens and Nixdorf merged to become Siemens Nixdorf. In 1998, Siemens Nixdorf split into Siemens Computer Systems (later Fujitsu Siemens Computers) and Wincor Nixdorf. See Fujitsu Siemens.
