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

`R_1R_2R_5 = R_3R_4R_6`

B

`1/R_5 + 1/R_6 = 1/(R_1+R_2) + 1/(R_3+R_4)`

C

`R_1R_4 = R_2R_3`

D

`R_1R_3 = R_2R_4 = R_5R_6`

Text Solution

Verified by Experts

The correct Answer is:
C
c. Since current I is independent of `R_6`, it follows that the
resistances `R_1, R_2, R_3, and R_4` must form a balanced Wheatstone
bridge.
