What is Inductance

  • Before defining inductance first of all, we will define an inductor.
  • Like capacitor, inductor is another component commonly in electronic circuits.
  • An inductor consists of a coil wound on a core or former of a suitable material like solid or laminated iron. core or ferrites which are highly ferromagnetic substances.
  • when a current through an inductor changes am emf is induced in it which opposes this change of current in the inductor.
  • This property of inductor or coil due to which it opposes change of current through it called the inductance denoted by letter L.
  • Unit of inductance is henry(H).
