== Inductors ==
 
 
 
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:
 
 
 
=== equation here soon ===
 
 
 
where
 
L = inductance ( units: henry )
 
V = voltage ( unit: volts )
 
I = current ( unit: Ampere )
 
t = time ( unit: seconds )
 
 
 
Uses:
 
*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.

Can be replaced in many circumstances with an impedance inverter using only an opamp, a capacitor, and a few resistors.
