Wheatstone bridge principle is used to measure the specific resistance 
of given wire, having length L, radius r. If X is the resistance of wire, then specific resistance is : 
.If the length of the wire gets doubled then the value of specific resistance will be :
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
As specific resistance does not depends on dimension of wire so, it will not change.
