Parallel capacitor model
There is a type of capacitor known as an electrolytic capacitor. The two "plates" are strips of aluminium foil separated by a conducting paste, or electrolyte. One of the foils is covered by an extremely thin layer of aluminium oxide, which has been electrolytically deposited, and it is this layer than forms the dielectric medium, not the ...
