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 580 sheets, the ream being 5.4 cm thick with sheets measuring 216 mm by 279 mm (the usual 8 1/2 by 11). What is the capacitance of the capacitor made this way if the dielectric constant of the paper is 3.7? (?0 = 8.85 × 10^?12 C2/N × m2)
