JEE Main 4 April 2024, Shift 1, Physics Q56

Question 56 of 90 in this shift, Physics question 26 of 30, Section B.

Twelve wires each having resistance 2 Ω2\ \Omega 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.

The figure, in words

Cube drawn in perspective with top face a-b-c-d and bottom face h-e-f-g (a above h, d above g, b above e, c above f); a 6 V battery is connected by an external wire across a and c (wire runs up from a, over the top, battery 6 V, down to c).
