f) A parallel plate capacitor is fabricated with plates of area 0.1 m2, and a dielectric of dielectric constant K = 13, one hundred microns (10011m) thick filling its gap. What is the capacitance? g) A capacitor of 128 pF stores a Joule of energy. What charge is on the plates? h) A capacitor of 128 stores a Joule of energy. What is the voltage between the plates? i) What is the sum of three and six? j) Gauss's Law was used in class to solve for the field around a sphere of charge enclosed in an uncharged thick sphere of metal. Explain why the technique used there would not work if the metal enclosure was a cube instead of a sphere.
