Twelve resistors, each of resistance R, are connected
Chapter 26, Problem 26.38(choose chapter or problem)
Twelve resistors, each of resistance R, are connected asthe edges of a cube as shown in Fig. 26-55. Determine theequivalent resistance (a) between points a and b, the ends ofa side; (b) between points a and c, the ends of a facediagonal; (c) betweenpoints a and d, the endsof the volume diagonal.[Hint: Apply an emf anddetermine currents; usesymmetry at junctions.]
