## Homework Statement

Identical resistors, R, make up the legs and rungs of a resistive ladder of infinite height. Find Req (equivalent resistance) of ladder, measured between points A and B.

## Homework Equations

## The Attempt at a Solution

Here's my thought process:

First make all the parallel resistors (the rungs) into one equivalent resistor. Since it's infinitely tall, this would be R^infinity/(infinity*R)

Second, find the total Req by adding the equivalent resistance for the rungs to the sum of the resistors on the legs. This would make Req=R^infinity/(infinity*R)+(infinity*R)

This makes Req equal to infinity.

But the answer is Req=(1+sqrt(3))*R

Is my process for setting this up wrong?
