If an electrical component is generating energy, there is must be another that helps store the energy that is unused. This is the main role of a capacitor, to help store electrical energy. Storing energy may seem like what a battery does. However, the main difference is that a battery can create new electrons as well and capacitor does not have this as a function. Interesting enough, any individual with two pieces of aluminum and a piece of paper (dielectric) can act as a capacitor. A capacitor’s size and type of dielectric, a non-conduction substance, determines whether the capacitor focuses on high frequency uses or high voltage programs. Did you know capacitors can power items from as small as a camera and to as big as powering a boat?
