A ring is made of a wire having a resistance R 0 = 12 Ω Ω . Find the points A and B as shown in the figure, at which a current carrying conductor should be connected so that the resistance R of the sub circuit between these points is equal to 
.
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
Initially 
Across point A & B, both branches will be in parallel connection.
Now 
So 
and 
For a uniform cross-sectional area, resistance will be proportional to the length of the wire.
Therefore,
