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_(1)R_(2)R_(5) = R_(3)R_(4)R_(6)`

B

`1/R_(5) + 1/R_(6) = 1/(R_(1) + R_(2)) + 1/(R_(3) + R_(4))`

C

`R_(1)R_(4) = R_(2)R_(3)`

D

`R_(1)R_(3) =R_(2)R_(4) = R_(5)R_(6)`

Text Solution

Verified by Experts

The correct Answer is:
C
If no current flows through `R_(6)`, then
`R_(1)/R_(2) = R_(3)/R_(4) rArr R_(1)R_(4) = R_(2)R_(3)`
