1. The problem statement, all variables and given/known data Suppose a resistor R lies along each edge of a cube (12 resistors in all) with connections at the corners. Find the equivalent resistance between two diagonally opposite corners of the cube 2. Relevant equations [tex]\Sigma[/tex]I = 0 at a node (a junction) [tex]\Sigma[/tex]V = 0 through a loop V=IR 3. The attempt at a solution Not quite sure how to do this one algebraically. Would I just add up all the V/Is? how?
