A wire of resistance 4R is bent in the form of a circle. What is the effective resistance between the ends of the diameter?

Text Solution

Verified by Experts

Here two resistance each of value 2R are connected in parallel as shown in figure

So the resistance between the ends A and B of a diameter of circle is
`R'= (2R xx2R)/(2R+2R)= R`
