The gap between the plates of a parallel-plate capacitor is filled with three equal-thickness layers of mica, paper, and a material of anknown dielectric constant. The area of each plate is 110 cm² and the capacitor's gap width is 3. 75 mm. The values of the known dielectric constants are Kmica = 6.5 and Kpaper = 3.75. The capacitance is measured and found to be 110 pF.
