Resistance of rod is 1 ohm. It is bent in the form of square. The resistance across adjoint corners is.

Answer: The answer to the question is 0.25 ohms

Explanation:

R = u x/A ... 1

where u is chosen as the resistivity of

the rod, A is area of the rod and x is

chosen as the length of the rod.

Let R * be the resistance of the

lengths of the rod across the adjoints

Then R * = u1/4 ... 2

Comparing equation 1 and 2

R * = 1/4

=0.25ohms
