Definition: | for an inductive two-terminal element with terminals A and B, quotient of the total flux Ψ_{AB} between the terminals by the electric current i in the element
$L=\frac{{\Psi}_{\text{AB}}}{i}$ 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 = m | ||

$L=\frac{{\Psi}_{\text{AB}}}{i}$

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 = m^{2} s^{−2} kg A^{−2}.
