- An inductor is an electronic device which stores energy in the form of magnetic field. It opposes the changes in the current passing through it.
- An inductor is just a coil of wire around some kind of core. The core could be just air or it could be a magnet.
- The amount of magnetic field energy stored is called as Inductance.It is represented by the letter ‘L‘.
- Inductance is directly proportional to the number of turns in the coil.Inductance also depends on the radius of the coil and on the type of wire (material) around which the coil is wound.
