inductance

Definitions

General Science

  • noun a measure of the ability of a conductor to bring a voltage into itself when carrying an alternating current, e.g. during short times when the circuit is switched on or off

Computing

Construction

  • The process that occurs when one conductor is placed next to another carrying AC current. The ever-changing magnetic field that results will induce a current in the first conductor.

Electronics

  • The property of a circuit or conductor which opposes any change to the current flowing through it. That is, it opposes an applied current, and also opposes changes to an already established current. Inductance makes changes in current lag behind changes in voltage. When quantifying inductance, some multiple of henrys, such as millihenrys or microhenrys is used. Also called electrical inertia.
  • The property of a circuit in which a varying current induces an emf in itself or in a neighboring circuit. When the emf is induced in the same circuit it is called self-induction, and when the emf is induced in another circuit it is called mutual induction. The symbol for self-induction is L, and for mutual induction it is M. When quantifying inductance, some multiple of henrys, such as millihenrys or microhenrys is used.
