Awhile back there was a thread on here about a resistor cube. A similar problem has come up in my physics class, the only difference being that the resistors have been replaced with 1pF capacitors. I flattened out the cube: ...and noticed that the A and B nodes are three capacitors in parallel each. However, in the middles section, while the pairs of capacitors coming off of the initial (red) node share a common node each, they do not on the other (blue) side. So, they are not truly in parallel. However, since they are all equal, I surmised that they would behave as if they were in parallel, and I come up with this: Can anyone offer any corrections to my solution or suggestions for a better method?
