Answer:
2Ω
Explanation:
Effective resistance across the diameter = 8 Ω (Given)
Since, the wire is bent into a circle, thus each of the semicircular arc will get a resistance of 4 Ω
Therefore both are parallel in the current distribution.
R = p1/A
= 1/R between A nd B = 1/4 + 1/4
= 1/R = 2/4
= R = 4/2
= R = 2
Thus, the resistance of the wire is 2Ω.
