Pretend R2 and C2 are a single reactance. Call it Z2. Now, Z2 is in series with C1. Call C1's reactance Z1. The impedance of that branch is thus (Z1 + Z2) in parallel with R1. In reverse, the impedance is (Z2 + Z1) in parallel with R1. So, does the order matter?
I could not resist this one . I'm also from sweden so english is not my native languish.
You and your "dude mate" did the same drawing exept he was standing on his head, thats why it was different drawn. ti hi hi
