| for an inductive two-terminal element with terminals A and B, quotient of the linked flux Ψ between the terminals by the electric current i in the element |
where the sign of the linked flux is determined by taking the voltage, in the time integral defining it, as the difference of the electric potentials at terminals at A and B, and where the current is taken as positive if its direction is from A to B and negative if its direction is from B to A
Note 1 to entry: An inductance cannot be negative.
Note 2 to entry: In French, the term “inductance” is also a short term for “bobine d’inductance”, in English “inductor” (151-13-25).
Note 3 to entry: The coherent SI unit of inductance is henry, H.
