Two capacitors, one that has a capacitance of 3.90 µF and one that has a capacitance of 12.3 µF, are connected in parallel. The parallel combination is then connected across the terminals of a 11.0-V battery. Next, they are carefully disconneted so that tehy are not discharged. They are then reconnected to each other--the positive plate of each capacitor connected to the negative plate of the other.
(a) Find the potential difference across each capacitor after they are reconnected. 3.90 µF capacitor ?V = 12.3 µF capacitor ?V =
(b) Find the energy stored in the capacitors before they are disconnceted from the battery, and find the energy stored after they are reconnected. before disconnected ? mJ after reconnected ? mJ
