# Help drawing equivalent resistor diagrams.

1. The problem statement, all variables and given/known data
I really just need help understanding how to re-draw a resistor diagram after calculating an equivalent resistor.
Now in the picture given in the attachment, you can see that R1 and R6 are in series with eachother
when I compute their equivalent resistor(R1+R6), on what location on the system of resistors would I place the equivalent resistor? Would I place it in the location of R1, R6, or some intermediate point in between? I know that no matter which of the three choices I pick, it'll still be in parallel with R2 but I'm just looking for clarity in the expected placement.

2. Relevant equations

3. The attempt at a solution

You can place it anywhere, at any orientation you wish, so long as its leads connect across R2.

Orientation (angle, position) doesn't matter to a circuit. The lengths and convolutions of wires doesn't matter; they can wander all over the page at any angle or curve about with wild abandon. Only the underlying topology, in the mathematical sense, regarding what connects to what, matters.
