Siemens (S) is the SI derived unit of of electrical conductance of a conductor in which a current of one ampere is produced by an electrical potential difference of one volt (S = A∙V-1 = Ω-1). The unit is named after the German scientist Ernst Werner von Siemens (1816-1892).
Metric unit of conductance.
the SI unit of electric conductance, susceptance, and admittance. The most important property of a conductor is the amount of current it will carry when a voltage is applied. Current flow is opposed by resistance in all circuits, and by also by reactance and impedance in alternating current circuits (see ohm). Conductance, susceptance, and admittance are the inverses of resistance, reactance, and impedance, respectively. To measure these properties, the siemens is the reciprocal of the ohm. In other words, the conductance, susceptance, or admittance, in siemens, is simply 1 divided by the resistance, reactance or impedance, respectively, in ohms. The unit is named for the German electrical engineer Werner von Siemens (1816-1892). See also mho.
the SI unit of conductance, symbol S, equivalent to the reciprocal ohm (Ω); named after William (Wilhelm) Siemens (1823 - 1883), engineer.
(S, upside-down ) absolute ohm; ohm-1; reciprocal ohm; mho. Compare with conductance. The SI unit of electrical conductance. A material has a conductance of one siemens if one ampere of electric current can pass through it per volt of electric potential.
a unit of conductance equal to the reciprocal of an ohm
engineer who was a brother of Ernst Werner von Siemens and who moved to England (1823-1883)
a measurement of current conductance (often abbreviated "G") thru ion channels and is abbreviated "S". Is equal to the ratio of current (measured in amps) divided by voltage (measured in volts). (note: this comes from ohm's law) It also equals 1/R. 1 picosiemen equals 10^-12 siemens and is convenient to use for ion channels. For example, the ion channel gramicidin has a conductance of 30 pS for cations. This is equalivant to 6.28 X 10^6 ions per second per applied volt of conductance of cations thru the pore when the concentration of cations is equal on both sides of the membrane.
the SI unit of electric conductance. The most important property of a conductor is the amount of current it will carry when a voltage is applied. A conductor has a conductance of one siemens if it carries one ampere of current per volt of potential. Conductance is the inverse of resistance, and the siemens is the reciprocal of the ohm. In other words, the conductance, in siemens, is simply 1 divided by the resistance, in ohms. The unit is named for the German electrical engineer Werner von Siemens (1816-1892).
(micro- or milli-) Unit of conductance of a solution. This value is the product of solution conductivity (L) in siemens/cm and the cell constant Kc/cm. The conductance of a solution in siemens (S) is the reciprocal of its resistance in ohms. Formerly known as the Mho ( ); reciprocal of (ohm).
The new and preferred term for MHO.
The siemens (symbol: S) is the SI derived unit of electric conductance. It is named after the German inventor and industrialist Ernst Werner von Siemens, and is equivalent to the now-obsolete mho. In English, it is siemens in both singular and plural.
The Siemens MOMO Train (Modular Metro, originally NEXAS, but more generally Siemens train) is a type of electric train that operates on the suburban railway network of Melbourne, Australia. Introduced to service in 2003 and built by Siemens AG, the electric multiple unit trains are the newest in the city's suburban fleet.
