"C is for Capacitor" - Circuit Playground Episode 3! Learn all about electronics and how capacitors work with Ladyada, Cappy and ADABOT!

A capacitor stores electrons using an electric field. The capacitor has two separated plates, where electrons are held. A voltage placed across the capacitor makes the electrons want to move from one plate to the other, but a 'dielectric' between the plates is there to make sure that they don't. The electrons can be stored on the plates until they are needed to make a circuit.
