In the figure below, a potential difference V = 150 V is applied across a capacitor arrangement with capacitances C1 = 12.0µF, C2 = 6.00µF, and C3 = 16.0µF. Find the following values. Here's the diagram: http://www.webassign.net/hrw/hrw7_25-28.gif I already solved this problem but I'm having some trouble understanding the concept behind it. I know that capacitors 1 and 2 are in parallel and that they are in series with capacitor 3, but I don't understand why. Especially because capacitors 1 and 2 aren't parallel in the way I'm used to seeing parallel capacitors, like this: http://www.rapidtables.com/electric/capacitor/parallel capacitors circuit.GIF. Also, if you combine 1 and 2 in parallel, what does the resulting capacitor even look like? I'm having trouble visualizing this. Can anyone help me understand this problem? I would really appreciate it.
