A wire is bent in the form of uniform circular ring. A and B are two points on the ring such that AOB 60, where O is the centre of ring. If the equivalent resistance across A and B is 5 what is the resistance of whole wire?

Electromagnetism is an interaction that occurs between particles with electric charge via electromagnetic fields. The electromagnetic force is one of the four fundamental forces of nature. It is the dominant force in the interactions of atoms and molecules.
