Question

if 12 capacitors are connected in the edges of the cube find the equivalent capacitance on the same side of the cube

Answer 1

Answer:

6/5 C. Let ABCD and EFGH be opposite faces of the cube, with A and G cube corners lying on the same body diagonal. If potential is applied across A and G, it is clear by symmetry that the cube corners B,D,E are at the same potential. Similarly the remaining cube corners F,H and C are at the same potential. This helps to reduce the circuit to planar geometry which is easily solved to get the above answer.
