How Capacitors Store and Release Energy


 Based in Southern California, Dianoush Emami has managed numerous construction and engineering actives, with a focus on complex utility and general facility projects. Dianoush Emami has guided various applications involving the transmission and distribution of high-voltage electricity.


One of the essential electrical components for storing energy is the capacitor. A battery is quick to charge, and relies on chemical reactions for the release of energy and thus has a slow discharge rate. By contrast the capacitor, as a circuit component, stores electrical energy temporarily via a process of distributing charged particles across a pair of plates, which creates a difference in potential. Requiring less time than a battery to charge, the capacitor is also able to release its energy very quickly.


Capacitors have a variety of uses, with mylar capacitors commonly employed in timer circuits such as alarm clocks and ceramic capacitors employed with high frequency applications such as X-ray or MRI equipment. Super capacitors are used in powering hybrid and electric vehicles, while those made of glass support high-voltage applications. Within these various capacitors, terminals connect with two metal plates that are separated by a dielectric, or a non-conducting substance.


Capacitors are engaged by being connected with a battery or other power source, with one plate connected to its negative terminal and one to its positive terminal. A good way of envisioning the capacitor and its storage and release of electrons is as a water tower connected to a water pipe. The tower stores water pressure when there is excess water that a community cannot readily consume, and releases water when it’s needed at a time of high demand.
