1. The problem statement, all variables and given/known data Two capacitors, with capacitances of 4.10 uF and 5.90 uF are connected in parallel across a 660-V supply line. The first questions all relate to finding the charges on each capacitor and the voltage accross each one. I can do all of these with no problems. But then it asks "The charged capacitors are disconnected from the line and from each other, and then reconnected to each other with terminals of unlike sign together. Find the final charge on the 4.10 uF capacitor." 2. Relevant equations Q=CV CT = C1 + C2 3. The attempt at a solution I don't really understand what will happen in this situation. The battery is now disconnected so the voltage can change accross each capacitor, but the charge should be conserved shouldn't it? Or will they somehow discharge? Please help!
