Definition

For a administering or semiconducting aspect with electrical attrition R, the conductance G is authentic as

G = \frac{1}R = \frac{I}V

where I is the electric accepted through the article and V is the voltage (electrical abeyant difference) beyond the object.

The assemblage siemens for the conductance G is authentic by

\mbox{S} = \Omega^{-1} = \dfrac{\mbox{A}}{\mbox{V}}

where Ω is the ohm, A is the ampere, and V is the volt.

For a accessory with a conductance of one siemens, the electric accepted through the accessory will access by one ampere for every access of one volt of electric abeyant aberration beyond the device.

Example: The conductance of a resistor with attrition six ohms is G = 1/(6 Ω) ≈ 0.167 S ≈ 167 mS.
