Capacitance Problem 15: The gap between the plates of a parallel-plate capacitor is filled with three equal-thickness layers of mica, paper, and a material of unknown dielectric constant. The area of each plate is 120 cm2 and the capacitor’s gap width is 3.25 mm. The values of the known dielectric constants are Kmica = 6.5 and Kpaper = 3.25. The capacitance is measured and found to be 105 pF.Find the value of the dielectric constant of the unknown material.
