Resistance of a wire is 
. If it is formed in shape of square, the resistance across its diagonal is R 1 . If it is formed in shape of circle, then resistance across its diameter is R 2 then find 
?

D
Text Solution
Verified by ExpertsThe correct answer is:
A
Since the wire is bent in the form of the square, each side of the square will have same resistance, i.e., 5 Ω.
Resistance between the end of a diagonal,
Similarly, each half circumference will have 
each of resistance.
Resistance along the diameter is
