YT2095 Posted August 30, 2003 Posted August 30, 2003 here is a question that we were asked in electronics class a few years ago, we`de just learned Ohms law. Non of us ever managed to work it out here goes..... Imagine a cube made of (100 Ohm) resistors. so that would be a total of 12 identical resistors. work out using ohms law, the resistance between the front left bottom corner, and the top right back corner. A diagonal thing. each edge is a 100 Ohm resistor. I don`t think it`s possible myself using just ohms law, but would love to be shown either way, and certainly the answer!
Kedas Posted August 30, 2003 Posted August 30, 2003 different ways: http://home.tiscali.be/kpmoerman/special/special.htm#cube Obviouly the smart way is the one you were supposed to find. Easy when you know the answer. I didn't know it either when that problem was given to me. (I burried myself under with star to triangle calculations)
YT2095 Posted August 30, 2003 Author Posted August 30, 2003 Kedas, yer a diamond mate!!! thnx a bunch for the data, I`ve added that url to my favorites too. it`s no wonder we could never work it just being taught Ohms law btw, I like the chaos circuit, we used to use something similar for white noise generators (for synths) using Zener Diode breakdown noise through an OP Amp There`s a neat way using TTL shift registers too, I`ve lost the diag though. cheers for the site again
deonm Posted July 4, 2009 Posted July 4, 2009 Hi This was one of those things I always wanted to solve comprehensively. See the attachment. Regards Deon ResCube.txt
