In the given circuit, it is observed that the current I is independent of the value of the resistance R 6 . Then the resistance values must satisfy
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
As I is independent of R 6 no current flows through R 6 this requires that the junction of R 1 and R 2 is at the same potential as the junction of R 3 and R 4 . This must satisfy the condition 
as in the Wheatstone bridge.
