A capacitor can be made from two sheets of aluminum foil separated by a sheet of waxed paper. If the sheets of aluminum are $0.30 \mathrm{m}$ by $0.40 \mathrm{m}$ and the waxed paper, of slightly larger dimensions, is of thickness $0.030 \mathrm{mm}$ and dielectric constant $\kappa=2.5,$ what is the capacitance of this capacitor?
A capacitor can be made from two sheets of aluminum foil separated by a sheet of waxed paper. If the sheets of aluminum are 0.150 m by 0.230 m and the waxed paper, of slightly larger dimensions, is of thickness 0.0700 mm and dielectric constant Îş = 2.50, what is the capacitance of the capacitor? nF

A capacitor is made by taking two sheets of aluminum foil, each 0.022 mm thick, and placing between them a sheet of paper which comes from a ream of 500 sheets. The ream is 5.5 cm thick with sheets measuring 216 mm by 279 mm. What is the capacitance of the capacitor made this way if the dielectric constant of the paper is 3.7? THE ANSWER SHOULD BE (18nF)
