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 fig.

There is an infinite wire grid with square cells (Fig). The resistance of each wire between neighbouring joint connections is equal to R_(0) . Find the resistance R of the whole grid between points A and B . Instruction. Make use of principles of symmetry and superposition.

A wire has resistance 12 ohms. If it is bent in the form of a equilateral triangle. The resistance between any two terminals in ohms is:

Three resistances 4Omega each of are connected in the form of an equilateral triangle. The effective resistance between two corners is

In the circuit shown in figure, each resistance is Net resistance between points A and B is

In the circuit shown in figure, each resistance is Net resistance between points A and B is
