Two capacitors are connected in parallel to each other and a battery. There are two switches, S1 between the first capacitor and the battery and S2 between the two capacitors. At first, S2 is open and S1 closed, so the first capacitor charges, then S1 is opened and S2 closed, so the charge is shared between the two capacitors. My question is why are the two capacitor still considered to be in parallel when S1 is open. Here's a link to the actual question where the scenario came up, question 1 d: http://www.ocr.org.uk/download/pp_10_jun/ocr_57573_pp_10_jun_gce_g485.pdf" [Broken] This isn't homework, I'm just struggling witht he concept, it seems as if it should be in series when S1 is open, but apparently not? Thank you in advanced for your explanations, LorentzForce.
