Aluminum electrolytic capacitors are made of two aluminum foils and a paper soaked in electrolyte. The anode aluminum foil is anodized to form a very thin oxide layer on one side and the unanodized aluminum acts as cathode; the anode and cathode are separated by paper soaked in electrolyte, as shown in Fig. 8.10A and B.The oxide layer serves as a

Capacitors store energy by holding apart pairs of opposite charges. Since a positive charge and a negative charge attract each other and naturally want to come together, when they are held a fixed distance apart (for example, by a gap of insulating material such as air), their mutual attraction stores potential energy that is released if they are re-united.
