(b) A good capacitor is required to have a higher energy storage, but lower leakage resistance. Based on these requirements, select the dielectric material for a spherical capacitor which include an inner conductor at a = 1 cm, and an outer conductor at b = 5 cm. The properties of the proposed dielectric materials are given in Table 2b. Table 2b: Dielectric Material Properties. Materials #1: Bakelite Dielectric Constant Er Dielectric Strength E #2: Mica 5 6 20 M V/m 70 M V/m Conductivity o 10-10 siemens/m 10-15 siemens/m
