Homework Statement
Here is an interesting problem... there is a wire bent in the shape of an equilateral triangle, side length = a and resistivity = rho.
In the center of this triangle is another equilateral triangle (inverted, side = a/2, resistivity = rho) and so on into infinity. What is the overall resistance between points A and B in terms of a and rho?
Homework Equations
R = (rho * length)/area
The Attempt at a Solution
I started by using the equation for resistivity, R = (rho * length)/area, but I wasn't sure if area would apply here. We aren't given any information about the wire beyond the shape and length. So I'm really asking for help in determining a good starting point... I don't know of any other equations that would incorporate rho and length.
