A wire of resistance $10 \Omega$ is bent in form of closed cirle. How do I find resistance across its diameter.
Please don't consider this problem as homework question, just provide some hints, and make the problem clear, i.e. if we had to bent wire and made diameter also with this wire or only circle not diameter with this wire. What is actual meaning of across diameter, please make it clear by providing even rough diagram, please, it would be great help.
