|
An Inductor is a component that stores energy in a magnetic field. It does this
|
|
|
|
|
by using a current flowing through a coil of wire, often around a magnet.
|
|
|
|
|
Inductance is measured in Henery's (H)

Inductors are resistant to changes in current, and therefore can be used to
|
|
|
|
|
smooth out sudden changes. They also cause AC signals voltage and current to
|
|
|
|
|
get out of sync.

Inductors can wirelessly couple if their coils are placed in the same plane,
|
|
|
|
|
due to the induced magnetic field. This may cause currents to generate in
|
|
|
|
|
issolated coils if their fields are aligned.

|
|
When in series, the total inductors value is added together.
|
|
|
|
|
|
|
|
|
|
When in parallel, the total inductance is equal to the reciprical of the sum of
|
|
|
|
|
recipricals. This means that for three inductors L1 L2 and L3, the total
|
|
|
|
|
inductance of them in parallel is
|
|
|
|
|
|
|
|
|
|
Total = 1/(1/L1 + 1/L2 + 1/L3)
