iLC Circuits
LC circuits are a combination of inductance (L) and capacitance (C). A common instance of an LC circuit is the Varitone[1] knob of a Les Paul guitar.
Every LC circuit has a resonant frequency, which is the frequency at which the inductive reactance is the same as the capacitive reactance. When at "resonance", an LC circuit can store energy, as the energy oscillates between the magnetic field of the inductor and the capacitor.
WARNING! Even in low-power equipment, the energy stored inside an LC circuit can be dangerous!
