Equivalent resistor of 2011 resistor web

Click For Summary

Homework Help Overview

The discussion revolves around finding the equivalent resistance of a network of 2011 points, each connected by a resistor R. Participants are exploring the implications of symmetry in the circuit and how it affects the equivalent resistance between points.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants are questioning the geometry of the points and the implications of symmetry on voltage across the points. There are attempts to clarify the problem's setup and to explore the equivalent resistance for smaller configurations (3 and 4 points) as a means to generalize for larger configurations.

Discussion Status

The discussion is ongoing, with participants sharing diagrams and seeking clarification on the problem's details. Some have noted that traditional methods like Kirchhoff's laws may not be practical for the larger system, while others are exploring potential tricks or alternative approaches to simplify the analysis.

Contextual Notes

Participants have mentioned the requirement to show work on school assignments and the context of the problem being assigned by a teacher. There is a recognition that the problem may lead to complex systems of equations, particularly as the number of points increases.

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?

The Attempt at a Solution


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.
