1. The problem statement, all variables and given/known data The potential across a 3uF capacitor is 12V when it is not connected to anything. It is then conntected in parallel with an uncharged 6uF capacitor. At equilibrium, the charge q on the 3uF capacitor and the potential difference V across it are a)q=12uC, V=4V b)q=24uC, V=8V c)q=36uC, V=12V d)q=12uC, V=6V 2. Relevant equations q=CV Parallel connections C(total)=C1+C2 3. The attempt at a solution The answer is a) but I am not sure why. The first part of the question confuses me. I don't really know what it means when they say that it is not connected to anything. Thanks.
