1. The problem statement, all variables and given/known data A 10μF capacitor is charged to 5V and then isolated. It is then connected across a second uncharged capacitor of capacitance 15μF. The potential difference, in V, across both capacitors is A) 0.2 B) 0.5 C) 2 D) 3 2. Relevant equations C= Q/V Ct=C1+C2 3. The attempt at a solution Finding the charge of the first capacitor and trying to use this to find charge of the other to find voltage. Find the energy stored in the first capacitor and assuming this is the charge available to the second capacitor. Various other shifting about and substituting of equations. Nothing worked!
