1. The problem statement, all variables and given/known data Two capacitors of 34.0 μF and 125 μF are separately charged to 126 μC and 250 μC, respectively. They are then attached in parallel so that the + plate of one goes to the - plate of the other, and vice versa. Determine the final voltage across the two plates. 2. Relevant equations C=Q/Vc 3. The attempt at a solution I calculated the change in voltage by adding Q1 and Q2 and then dividing by the sum of C1 and C2. (126+250)/(34+125)=2.36 V. How do I find the initial voltage so that I can get the final voltage?
