Problem 5: An Isolated Capacitor with Charge A capacitor with capacitance C is charged by an amount Q. It 1s 1solated and not connected to a battery or any other electrical components. Insulating handles are used to increase the plate separation to 2d. a) b) How the voltage across the capacitor changes (or does not) in this problem and the last one. Does this make sense in terms of how the potential is defined. V = [E - dI
