18.5 Capacitors and Dielectrics

To introduce the idea of energy storage, discuss with students other mechanisms of storing energy, such as dams or batteries. Notice that the electric-field lines in the capacitor with the dielectric are spaced farther apart than the electric-field lines in the capacitor with no dielectric. This means that the electric field in the
