## Solve diagonal resistance of resistor 3D mesh.

Diagonal resistance of regular polyhedron. R(4)=1/2, R(6)=5/6. How about R(8), R(12) and R(20)?

## Re: Solve diagonal resistance of resistor 3D mesh.

Hi,

A simplification of the network topology allows you to easily apply Thevenin's theorem:

the solution you have provided is more accurate, thanks for sharing this with use... this will really help to other also tellpopeyes!

## Re: Solve diagonal resistance of resistor 3D mesh.

Note that this is a different network than the original network of Ttokoro.

If the entrance is at the top (as shown) then the exit should be at the crossing of Z7, Z11 and Z12, not on the crossing of Z2, Z3 and Z7!

Success!

## Re: Solve diagonal resistance of resistor 3D mesh.

In fact, I referred to the network (1) in the photo, instead I should have analyze the (2):

The diagonal resistance of resistor 3D mesh is 5/6 ohm.

Each branch resister is 1 ohm.

Infinity 2D mesh. RCD=4/π-1/2. This is Google puzzle.

How about Infinity 3D mesh. R(0,0,0)-(1,1,2)

in the infinity 3D mesh. The answer is

This is well known 1/3.
