|
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.
