Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of polarized capacitor which uses an electrolyte to achieve a larger capacitance than other types. As with other capacitors, aluminum electrolytic capacitors are made up of two electrically conductive plates separated by an insulator. However, unlike other capacitors, the aluminum electrolytes contain a solvent which acts as one of the plates, to achieve a large capacitance.
