Ok then, Ap physics 2 essentials

Question

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.

Checked:

A) B=D, C, A, E;  D, B=C, A=E

There is a typo in an early edition of the book

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.

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.

What do you mean by "short"?
