Twelve wires each having resistance 2 are joined to form a cube. A battery of 6 ~V emf is joined across point a and c . The voltage difference between e and f is ______V.

Correct answer

0

Step-by-step solution

From symmetry, current through e-b & g-d =0 aligned & R _ eq = 3 4 R = 3 2 & Current through battery = 6 2 3 =4 ~A & i ₂= 4 8 2=1 ~A & V across e-f = i ₂ 2 R = 1 2 2=1 ~V aligned
