Electricity.

1. inductance inducing an electromotive force in the same circuit in which the motivating change of current occurs, equal to the number of flux linkages per unit of current.

self-inductance

noun

1. L. Also called: coefficient of self-induction. the inherent inductance of a circuit, given by the ratio of the electromotive force produced in the circuit by self-induction to the rate of change of current producing it. It is usually expressed in henries
