dndfuf98 Posted April 1, 2017 Posted April 1, 2017 On gangnam style problem (AKA ap style), on number 7, I think the answer is C=D>A=B>E could you check on that. Quote
0 FizziksGuy Posted April 3, 2017 Posted April 3, 2017 Checked: A) B=D, C, A, E; D, B=C, A=E There is a typo in an early edition of the book Quote
0 dndfuf98 Posted April 3, 2017 Author Posted April 3, 2017 On A) of #7 of circuits of ap style, could you explain why your answer is right? I thought C and D had the most current immediately after closing because c has 2v/r and D also had 2v/r. Quote
0 FizziksGuy Posted April 4, 2017 Posted April 4, 2017 When the switch is first closed, the capacitor acts like a wire. Both B and D will have no effective resistance because there is a short from one side of the battery to the other where the capacitor is. For a split second, they will have near zero resistance, and a very large spike in current. Quote
