Hi All,

Please help me solve this problem:

What is the resistance between points A and B. All resistanses in the mesh are equal to R. The mesh size(NxN) is large.

I remember solving this problem when I was in school, but can't do it now

I also remember it has a very elegant solution.

If you know the answer, please give me a hint
