Last year I tried redrawing the cube in two dimensions and I could see how the vurrents were splitting but couldn’t solve it. Now here is a simpler solution that doesn’t require a lot of effort with whatever. I built the cube from 1k resistors and measured the value from corner to opposite corner, and got about, but not quite 833 ohms. So this solution correlates with my measurements. <\/p>\n\n\n\n
