Two copper wires are of same length one of the twice as thick as the other. Then the resistance of the two wires are in the ratio of:
Text Solution
Verified by ExpertsThe correct answer is:
C
Here: Thickness of first wire r 1 = 2r
The thickness of second wire r 2 = r
Using the relation for resistance of wire is,
R = 
Hence
