Electrical Energy and Capacitance 37 Answers to Even Numbered Conceptual Questions 2. Changing the area will change the capacitance and maximum charge but not the maximum voltage. The question does not allow you to increase the plate separation. You can increase the maximum operating voltage by inserting a material with higher dielectric strength between the plates. 4. Electric potential V is a measure of the potential energy per unit charge. Electrical potential energy, PE = QV , gives the energy of the total charge Q . 6. A sharp point on a charged conductor would produce a large electric field in the region near the point. An electric discharge could most easily take place at the point. 8. There are eight different combinations that use all three capacitors in the circuit. These combinations and their equivalent capacitances are: All three capacitors in series - 1 123 111 eq CCC C  =++   eq CCCC All three capacitors in parallel - = ++ One capacitor in series with a parallel combination of the other two:
