Homework Statement
2. Homework Equations [/B]
The Attempt at a Solution
so i was thinking i could take a look at small number of points and then generalize it but my method soon breaks down
in the diagram i have denoted the resistance of the segment beside it if there is a bracket it means how many of such branches there are in parallel to it i tried to conjecture some kind of pattern right in the next one i ran into some problems..
well for the four point situation the one on the right shows what i believe would be the equivalent transformed circuit but
1)for the case 3r looking at it there is actually two paths which has 3r the other one being the one that goes along the diagonal first then left and then back to end point
2) there also seems to be a path of 4r
here is picture of what i mean
i know such paths are not possible(can someone verify this for me it is just a gut feeling ) for at some point the current is going in the opposite direction but i don't know how to make mathematical pattern that would reject such paths
i was thinking of maybe assigning an appropriate numbering system and then imposing restrictions like the numbers need to be arranged in a non decreasing order this is a wild guess but maybe something along that line
or is my approach even valid here am i doing it totally wrong is there any other approach any help would be appreciated thanks
