The forms of practical capacitors vary widely, but all contain at least two conductors separated by a non-conductor. Capacitors used as parts of electrical systems, for example, consist of metal foils separated by a layer of insulating film. Electrolytic Capacitor A capacitor is a  passive   electronic component  consisting of a pair of  conductors  separated by a  dielectric  (insulator).
