Solution: A parallel-plate capacitor is connected to a battery and allowed to charge up. Now the battery is disconnected from the capacitor. The separation between the two plates is now decreased (the plates get closer together). What can we say about the potential energy stored by the capacitor? A) The potential energy increases B) The potential energy decreases C) The potential energy remains the same  D) Unable to determine from the information given.
