The siemens (symbol: S) is the SI derived unit of electric conductance. Siemens denote the reciprocal of resistance: one siemens is equal to the reciprocal of one ohm, and is sometimes refered to as the mho. It is named after the German inventor and industrialist Ernst Werner von Siemens. In English, the term siemens is used both for the singular and plural. The 14th General Conference on Weights and Measures approved the addition of the siemens ...

The siemens (symbol: S) is the SI derived unit of electric conductance. Siemens denote the reciprocal of resistance: one siemens is equal to the reciprocal of one ohm, and is sometimes refered to as the mho. It is named after the German inventor and industrialist Ernst Werner von Siemens. In English, the term siemens is used both for the singular and plural. The 14th General Conference on Weights and Measures approved the addition of the siemens as an SI derived unit in 1971.
For a physical object, typically an electronic device, with electrical resistance R, the conductance G is defined as
where I is the electric current through the object and V is the voltage (electrical potential difference) across the object.
The unit siemens for the conductance G is defined by
where A is the electric current in amperes, V is the electric potential in volts, and Ω is the electrical resistance in ohms.
For a device with a conductance of one siemens, the electric current through the device will...
