1. The problem statement, all variables and given/known data ;-------| |---------; | | | | '-------| |---------' Consider a capacitator of capacity C1 charged with a charge Q. Suppose you connect it in parallel to another capacitator, C2, initially uncharged. Find the final charge and difference of potencial at each condensator. 2. Relevant equations 3. The attempt at a solution I know that the initial charge Q will be equal to: Q = q1+q2 , where q1 and q2 is the final charge of capacitator 1 and 2. The difference of potential, V, is equal in both the capacitators. Therefore I can say that q1 = Q - q2 = Q - C2/V = [ QV - C2 ] / V I don't know where to go from here. I don't think I can get anywhere... If anyone could point me in the right direction I'd really appreciate! Thanks.
