Just a little light hearted puzzle to keep the grey matter active over Christmas when you are not busy with the soldering iron!
A plastic cube has a 10ohm resistor laid along each of its 12 edges. At each corner the ends of the three meeting resistors are connected together.
What is the resistance between two furthest corners? :?
Happy Xmas to everyone.
