Q. Twelve wires of equal length and same cross-section are connected in the form of a cube. If the resistance of each of the wires is $R,$ then the effective resistance between the two diagonal ends would be
A) $2\ R$
B) $12\ R$
C) $\frac{5}{6}R$
D) $8\ R$
Explanation
(c) The given circuit can be simplified as follows
$\therefore R_{AD} = \frac{5R}{6}$
