1. The problem statement, all variables and given/known data A 3.0 µF capacitor charged to 40 V and a 5.0 µF capacitor charged to 18 V are connected to each other, with the positive plate of each connected to the negative plate of the other. b. Find the potential difference across the capacitors. 3. The attempt at a solution Do you just add up the potentail differences? 18 + 40 = 58V?
