Question

A wire of resistance 20Ω is bent in the form of a closed circle. What is the resistance between

any two diametrically opposite ends..​

Answer 1

Answer:

after bending the wire in the form of a circle the resistance at two diametrically opposite ends will be 10 ohms. bcoz the arrangement now resembles a parallel circuit.

and in parallel connection the equivalent resistance is R/n for 'n' no of equal resistors.
