Above figure shows that paper capacitor. In this, a paper soaked in oil or wax is used as the dielectric in between the tin foils that serve as a parallel plates. In order to increase the capacitance to large extent, several number of tin foils and wax papers to be used by arranging alternatively as shown in figure.This entire capacitor can be rolled and sealed in a cylinder. Since, these capacitors occupy small space and are cheaper in cost and they are widely used in radio circuits and in laboratories.
