Equivalent resistor of 2011 resistor web

AI Thread Summary
The discussion revolves around finding the equivalent resistance between pairs of points connected by resistors in a network of 2011 points. Due to the symmetry of the arrangement, the equivalent resistance between any two arbitrary points remains constant. Participants note that while calculating for smaller numbers of points is straightforward, the complexity increases significantly with more points, making traditional methods like Kirchhoff's laws impractical. The conversation suggests that a generalization can be made regarding the equipotential nature of the points, but a specific solution for larger configurations remains elusive. Overall, the need for a simpler method or trick to solve this problem is emphasized.

1. let's have 2011 point each pair connected by a resitor R. what is the equivalent resistor between each pair of points conneced by R?



2. due to the symmetry the equivalent resistor between two arbitrary point connected by R is always the same. let's take two of this contigouspoins. the voltage at each other point is the same, due to the symmetry (is it right?), but then?

Can you please describe the problem in more detail, and maybe show us a diagram?

What do you mean by 2011 points? What is their geometry? 2-dimensional, 3-dimensional? What shape?
 
in attachment a diagram for 5 points.

You are required to show your work on schoolwork questions. What is the answer for 3 poinsts? For 5 points? etc.

And where did this question come from?
 
it is a question from our teacher.
it is evident that using standard method of resolution (kirchoff or whatever) is absurd, as it would get to a big linear sistem of equations.
for three is easy Req=2/3R. for four, it' s eay as well, as for symmetry reason the free twi point are at hte same voltage, so Req=R/2.
but 5, 6 , 7 ...2011 points? is the generalization that all the other points are equipotential corrct?
 
Of course Kirchoff is not an option.
But it looks like you already know the solution, at least partially.
 
I would like, but I do not have.
there must be some trick.
isn't there on line in the WEB any free circuit resolutor?

Not in this case.
But your intuition was fine.
