The space between capacitors may simply be a vacuum, and, in that case, a capacitor is then known as a "vacuum capacitor." However, the space is usually filled with an insulating material known as a dielectric. 8.3: Capacitors in Series and in Parallel Several capacitors can be connected together to be used in a variety of applications.
