1. The problem statement, all variables and given/known data Reduce the circuit below into a single equivalent capacitor at terminals a,b. Assume all initial voltages at t = 0 are zero. 2. Relevant equations 3. The attempt at a solution Okay, this is the circuit I had in mind when I made this thread earlier https://www.physicsforums.com/showthread.php?p=4684447#post4684447 My first thought was to take all the capacitors that to me look to be in parallel and combine them. I said that they are in parallel because they share at least 2 nodes on both sides of the components. Then, I said the capacitors on the left side are in series. There is a lot of doubt in my decision here. I say that because they all 3 share the same node on only one side of their component, so I called them in series. Then, after that the rest are clearly in series so I combined them. Also, I wonder why it matters what terminals I choose to find the equivalent capacitance between, and what would happen if I chose different terminals?
