| for a resistive two-terminal element or two-terminal circuit with terminals A and B, quotient of the electric current i in the element or circuit by the voltage uAB (131-11-56) between the terminals |
where the electric current is taken positive if its direction is from A to B and negative if its direction is from B to A
Note 1 to entry: The conductance of an element or circuit is the inverse of its resistance.
Note 2 to entry: The term "conductance" is also a short term for “conductance to alternating current” (131-12-53).
Note 3 to entry: The coherent SI unit of conductance is siemens, S.
