Expert Answer:
A wire of resistance R is made to form a square. Hence, each side of the square will have resistance R/4.
When we want to find the resistance across any of the diagonal the equivalent circcuit is as shown above.
Two resistors will be in series and this series combination will be in parallel with the other series combination.
Hence, the equivalent series resistance will be
Now, the equivalent resistance between any of the diagonals will be
