6.1.2: Capacitance and Capacitors
A capacitor is a device that stores energy. Capacitors store energy in the form of an electric field. At its most simple, a capacitor can be little more than a pair of metal plates …
Capacitor
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other.
8.4: Energy Stored in a Capacitor
The energy (U_C) stored in a capacitor is electrostatic potential energy and is thus related to the charge Q and voltage V between the capacitor plates. A charged capacitor stores energy in the electrical field between its plates.
What is a Capacitor, And What is Capacitance?
What is a Capacitor? Capacitors are one of the three basic electronic components, along with resistors and inductors, that form the foundation of an electrical circuit a circuit, a capacitor acts as a charge …

OverviewHistoryTheory of operationNon-ideal behaviorCapacitor typesCapacitor markingsApplicationsHazards and safety
Natural capacitors have existed since prehistoric times. The most common example of natural capacitance are the static charges accumulated between clouds in the sky and the surface of the Earth, where the air between them serves as the dielectric. This results in bolts of lightning when the breakdown voltage of the air is exceeded.
