Consider a capacitor of capacitance C initially charged with charge Q. A second initially uncharged capacitor, also of capacitance C, is subsequently connected in parallel to the first capacitor. It is straight forward to show that charge state of the combined system, when it reaches equilibrium, is one where the charge divides between the capacitors, so that each capacitor now carries charge Q=2. However, it is interesting to note that the energy stored in the capacitors has changed between the...
