Two capacitors (C1=4.6μF, C2=16μF) are charged individually to (V1=15.3V, V2=6.9V). The two capacitors are then connected together in parallel with the positive plates together and the negative plates together. a)Calculate the final potential difference (in V) across the plates of the capacitors once they are connected. b)Following the connection in (a) above, calculate the amount of charge (absolute value, in C) that flows from one capacitor to the other when the capacitors are connected together. c) By how much (absolute value) is the total stored energy (in J) reduced when the two capacitors are connected?
