Equation 1: Leq = L1 + L2 + L3 + ...... Ln
In the figure below, the equivalent inductance is calculated using equation 1 as
Leq = 1mH + 2mH + 5mH = 8mH

Units
Inductance is measured in Henries (H). A milliHenry (mH) is one-thousandth of a Henry. Inductors generally range in value from nanoHenries (nH) to milliHenries. An inductor in the milliHenry range is a large inductor. Because of its size, it can store a large amount of energy. The more energy an inductor can store, the more power it can generate and the higher potential of dangerous electrical shock.
Electrical Specifications
Inductors have associated with them a resistance. They also have a rated current. The rated current should not be exceeded. For inductors in series, the inductor with the lowest rated current determines the maximum amount of current that the series circuit can safely pass.
Applications
Inductors are used as electronic filters, in induction motors and in transformers. They are also used extensively in power supplies. RF chip inductors are used in cell phones, local area networks and other high frequency circuits in the 10 MHz to GHz range.
