CEI CapacitorsWhat is a Capacitor?

A capacitor is an electrical component used to store energy. There are numerous types of capacitors but all consist of two types of conductors separated by a dielectric (insulator). The energy is stored in an electrostatic field when a potential difference across the conductors develops.  This is caused from a positive charge collecting on one plate and a negative charge collecting on the other.
