3. The relative permittivity of a material is the ratio of its permittivity to that of free space. The relative ratings of several common dielectrics are as follows: Dielectric Air Glass Mica Porcelain Teflon Relative Permittivity 1.001 7.500 5.000 6.000 2.000 Determine which of these dielectrics is used in the capacitor shown in the figure below (Fig. 12.34). Area = 5 x 10¹² m² C = 0.022 uF 1 x 10 m
