AP Physics C. Capacitors. A capacitor consists of 2 conductors of any shape placed near one another without touching.. It is common to fill up the region between these 2 conductors with an insulating material called a dielectric.. Capacitor. A . capacitor. is an electrical device that stores energy. Most electrical devices have some capacitance either intentional or accidental . The . energy is stored by maintaining a potential difference between two conductors. . plates of capacitor at. .
