Electronic Devices – Inductor

An inductor is a coil of wound on a core. An inductor opposes the sudden variation of current. an inductor stores the energy in the form of current in magnetic field. The coil blocks DC voltage.an inductor allows the Direct current

L=µ o µr A N2/l Henry

  • l=length of the core,
  • µ o=permeability of free space,
  • µr=relative permeability of the core material,
  • A=area of cross-section of the coil, N=length of the core,
