1. So my teacher gave us examples of how to solve capacitor problems. I know how to solve the problem but I don't this problem's particular "formation" of parallel capacitors. In this problem, my teacher says C3 and C4 are parallel but when I did the problem, I assumed it was series. Can anyone explain how C3 and C4 are parallel? I assumed there needed to be another capacitor directly across from them to become parallel, rather than in a 90 degree formation like C3 and C4.
