equivalent resistance of tricky circuits???

1. Homework Statement
what is the equivalent resistance between A and B? img002.jpg


2. Homework Equations
kirchoffs law for voltage and current


3. The Attempt at a Solution
i got the equivalent resistance between A to C as 3R/4
but i have to find the resistance between A to B but point B is in the middle of the circuit and i dont know how to approach it
i am stuck on this
please help!!!!!!!

What approach have you tried? Can you show your work so far?

Re: equivalent resistance of tricky circuits???

i have always calculated equivalent resistance at the ends
i dont have any idea how i would reach at point B which is in the middle

Re: equivalent resistance of tricky circuits???

The network of resistors is equivalent with a cube of resistors. You can use that the equivalent points are at equal potential if you connect a voltage source between points A and B, and can be connected with a wire.

A step ahead: The points D,E,G of the cube are equivalent and can be connected with a wire. The same holds for J, H, C.
