A wire of resistance `10(Omega)`is bent to form a complete circle.Find its resistance between two diametrically opposite points.

Text Solution

Verified by Experts

Let ABCDA be the wire of resistance 10(Omega). We have to claculate the resistance of this loop between the diametrically opposite points A and C. The wire ADC and ABC will have resistances `5(Omega)`each. These two are joined in parallel between A and C. The equivalent resistance R between A and C is therfore, given by
`R=(5(Omega)xx5(Omega))/(5(Omega)+5(Omega))=2.5(Omega).
