Determine the semi-infinite resistance between the circuit points A and B, if

resistance of each unit/link is equal to R.

Solution. Posted on Saturday, December 13, 2014.

In order to solve this problem, we have to simplify this circuit. From the symmetry of the circuit, it is clear that the electric potential of the point 1 equal to the electric potential of the point 6, the electric potential of the point 2 equal to the electric potential of the point 7 and etc. So, the new circuit will be

We could replace the new circuit by
