There is an infinite wire grid with cells in the form of equilateral triangles. The resistance of each wire between neighboring joint connections is \( R_{0} \). The net resistance of the whole grid between the points \( A \) and \( B \) as shown in figure is
(1) \( R_{0} \)
(2) \( \frac{R_{0}}{2} \)
(3) \( \frac{R_{0}}{3} \)
(4) \( \frac{R_{0}}{4} \)
