a question of electronics

[Homer_simpson]

i assumed that most people who know a thing or two about computers possibly know a thing or two about electronics so it seemed appropriate to post here.

this is a question of equivalent resistance and kirchoffs rule. All resistors in the circuit have the same resistance R. what is the equivalent resistance between point A and B. the two images that i've attached are one and the same one is the 2D projection of the other.

Obligatory:



Now, it's been too long since ECE101 days...

You could build that circuit in a lab and read the answer with a multimeter... but that doesn't give you much points for the solution steps.

If you run some current into A and out of B, you can apply KCL. Similarly if you throw a battery into the circuit, you can apply KVL.

Once you have a bunch of related formulas, throw them into Prolog and wait for it to crunch through the equations

LOOOL... I friggin loved that... its so true, but i can't help myself.

edit: nevermind btw i figured it out. =D
