A 14-pF capacitor is charged to 6.0 kV and then removed from the battery and connected to an uncharged 69-pF capacitor. (a) What is the new charge on each capacitor? Q14 = 14.17 Q69 = 69.83 V nC V nC (b) Find the energy stored in the 14-pF capacitor before it is disconnected from the battery, and the energy stored in the capacitors after they are connected to each other. U; = 252 Uf = 7.1407 Does the stored energy increase or decrease when the two capacitors are connected to each other? O Potential energy is neither gained nor lost. O Potential energy is lost. O Potential energy is gained.
