Inductor is an electrical component that stores energy in magnetic field.
The inductor is made of a coil of conducting wire.
In an electrical circuit schematics, the inductor marked with the letter L.
The inductance is measured in units of Henry [L].
Inductor reduce current in AC circuits and short circuit in DC circuits.

Inductors in series
For several inductors in series the total equivalent inductance is:
LTotal = L1+L2+L3+...
Inductors in parallel
For several inductors in parallel the total equivalent inductance is:
