Electrostatic Potential and Capacitance.

This chapter swaps forces and fields for energy. Because the electrostatic force is conservative, every point near a charge can be given a potential (work per unit charge), and every arrangement of charges a potential energy. The chapter finds the potential of a point charge, a dipole and a group of charges, links potential to field through equipotential surfaces, then turns to conductors, dielectrics and the capacitor: its capacitance, the effect of a dielectric, series and parallel combinations and the energy it stores.
