A uniform wire of resistance `9Omega` is bent to form an equilateral triangle. What is the effective resistance between any two corners of the triangle.

Text Solution

Verified by Experts

`R_(s)=R_(AB)+R_(BC)=3Omega+3Omega=6Omega.`
`R_(P)=(R_(s)R_(BC))/(R_(s)+R_(BC))=(6xx3)/(6+3)=18/9`
`R_(P)=2Omega`
