Symbol: L
Definition: for an inductive two-terminal element with terminals A and B, quotient of the total flux ΨAB between the terminals by the electric current i in the element

L= Ψ AB i MathType@MTEF@5@5@+= feaagKart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLn hiov2DGi1BTfMBaeXatLxBI9gBaerbd9wDYLwzYbItLDharqqtubsr 4rNCHbGeaGqipu0Je9sqqrpepC0xbbL8F4rqqrFfpeea0xe9Lq=Jc9 vqaqpepm0xbba9pwe9Q8fs0=yqaqpepae9pg0FirpepeKkFr0xfr=x fr=xb9adbaqaaeGacaGaciaabmqaamaabaabaaGcbaGaamitaiabg2 da9maalaaabaGaamiQdmaaBaaaleaacaqGbbGaaeOqaaqabaaakeaa caWGPbaaaaaa@3B9D@

where the sign of the total 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" (IEV 151-13-25).

Note 3 to entry: The coherent SI unit of inductance is henry, H = m2 s−2 kg A−2.
