In this image, C1 is 1 microfarad and C2 is 3 microfarads and both capacitors are charged with a potential difference of V = 100V.
S1 and S1 are closed.
The solution says this is in parallel, but I don't see how it is. It looks like it's set up in series to me. But even if it is in parallel, I thought the total charge would be 400 C, but the solution says the total charge is 200. Why is this?
