D

6R

Text Solution

Verified by Experts

The correct Answer is:
A
Thee quivalent circuitis shown in fig.Since the Wheat stone’s bridge is balanced, therefore no current will flowthrough the arm KL.Equivalent resistance between
AKM=R+ R= 2R
Equivalent resistance between ALM = R +
equivalent resistance between A and B is given by

`(1)/(R) = (1)/(2R) +(1)/(2R) = (2)/(2R) = (1)/(R)`
`i.e., R =R`
