What is a Capacitor? Definition, Uses & Formulas | Arrow

Capacitance is the ability of an object to store an electrical charge. While these devices'' physical constructions vary, capacitors involve a pair of conductive plates separated by a dielectric material. This material allows each plate to hold an equal and opposite charge. This stored charge can then release as needed into an electrical circuit.
