Definition: for a resistive two-terminal element or two-terminal circuit with terminals A and B, quotient of the voltage (131-11-56) uAB between the terminals by the electric current i in the element or circuit

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: A resistance cannot be negative.

Note 2 to entry: The term "resistance" is also a short term for “resistance to alternating current” (131-12-45).

Note 3 to entry: In French, the term "résistance" also denotes a device, in English "resistor" (see 151-13-19).

Note 4 to entry: The coherent SI unit of resistance is ohm, Ω.
