The famous cube built out of resistors of value "R":
For those who have never done this problem, it's a really good one. Build a cube where each side of the cube is a resistor whose value is "R", and then calculate the resistance:
1) Across diagonal points of the cube.
2) Across opposite corners on any face
3) Across any resistor's ends on any face.
The values should be in terms of "R".
See attached PDF.
Obviously, the answer is on the net but it's a very good problem because it requires recognizing symmetry, spatial visualization, and using equipotential nodes to simplify circuits.
I'll publish the answers later.
