| − | | |
| − | An inductor reacts to current, but not to its value, but rather its change. It “tries” to keep the current through it constant. Any change in current causes a voltage across the inductor. The key equation for an inductor ( it is a bit complicated, but anyway here it ) is:

| |
| − | *tuned circuits: a circuit that responds in a special way to some frequencies( s ).
| |
| − | *power supply filter: remove the pulsing DC left from rectification or other noise in the signal.
| |
| − | *Decoupling: usually blocking high frequencies from one part of a circuit from getting in another part.
| |
| − | *boost buck regulators: voltage regulators that decrease or increase voltage.

| − | == Transformers ==
| |
| − | | |
| − | Transformers are 2 or more inductors where the coils share the same magnetic field. This results in the current in one coil inducing a current in the other. They are commonly used to change the voltage from an AC source to a different voltage. We need much more description and information here. Would you add it?
