Definition: | for an inductive two-terminal element with terminals A and B, derivative of the total flux Ψ_{AB} between the terminals with respect to the electric current i in the element:
$L}_{\text{d}}=\frac{\mathrm{d}{\Psi}_{\text{AB}}}{\mathrm{d}i$ 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 A and B, and where the current is taken as positive if its direction is from A to B and negative in the opposite case Note 1 to entry: For an ideal inductor, the differential inductance | ||

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

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 A and B, and where the current is taken as positive if its direction is from A to B and negative in the opposite case

Note 1 to entry: For an ideal inductor, the differential inductance *L*_{d} is equal to its inductance *L*.
