Chapter 23: Electrostatic Energy and Capacitance

Chapter 23: Electrostatic Energy and Capacitance. Capacitor. Any two conductors separated by an insulator (or a vacuum) form a capacitor. In practice each conductor initially has zero net charge and electrons are transferred from one conductor to the other (charging the conductor).
