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).

How do fields create dipoles?

How do fields create dipoles?. E. -. +. Charges are not free to move in a dielectric! But electrons can be driven by E a bit away from the Nucleus without completely leaving it, creating an excess Charge on one side and a deficit on the other, ....
