1 Answer

Answer :

A plain foil dry electrolytic capacitor is made by forming a coating of aluminium oxide on both sides of an aluminium foil. Two strips of aluminium foil used are then separated by two layers of porous paper soaked with electrolyte. This assembly is rolled up the ends closed with wax and then sealed into an aluminium container.
