While lazing around flicking through the latest Diyode Magazine, I came across this little puzzle. What is the resistance across a cube of 1k resistors? (see image) There is a few nice ways to solve it, when insight comes to you. |
| IanB:
I would say 833.3 Ω ? Edit: I could even say 833⅓ Ω now that the forum has been upgraded :) |
| AlfBaz:
Easy, 12 x 1k resistors multiplied the alfbaz 1k cube constant of 0.069444' :-DD |

833.33... is correct. hamster_nz, did you deliberately angle the cube in your picture to make one of the insights more obvious, or is that just a coincidence? :D |

After all, you need some angle to show the cubic structure. But now that you've said that, there might be a few more who catch on. |
