Question

A regular hexagon with diagonals is made of
identical wires, each having same resistance
r, as shown in figure. Find the equivalent
resistance between the points A and B.

​

Answer 1

Answer:

Given A regular hexagon with diagonals is made of identical wires, each having same resistance r, as shown in 7.3.54. Find the equivalent resistance between the points A and B.

We need to calculate the equivalent resistance between the points A and B.

Now we have a regular hexagon. There are same resistance of r ohms. The ends are given by A and B.

So we have the currents as i 1, i2 and I – i1 – i2 on both sides (symmetry)

So we have 2r + 2r/3 = 8r/3 . 2r and 8r/3

So these three are in parallel.

Therefore 1/R eq = 3/8r + 1/2r + 3/8r

                              = 3 + 4 + 3 / 8r

                              = 10 / 8 r

                            = 5/4r

So R equivalent = 4/5r

                            = 0.8 r
