To present capacitors, this section emphasizes their capacity to store energy. Dielectrics are introduced as a way to increase the amount of energy that can be stored in a capacitor. To introduce the idea of energy storage, discuss with students other mechanisms of storing energy, such as dams or batteries. Ask which have greater capacity.
Capacitors are insulators, so the current measured in any circuit containing capacitors is the movement of the free electrons from the positive side of a capacitor to the negative side of that capacitor or another capacitor. The current does not flow through the capacitor, as current does not flow through insulators. When the capacitor voltage equals the …
