In the Wheatstone bridge shown below, in order to balance the bridge, we must have-

A

`R_(1) = 3 Omega, R_(2) = 3 Omega`

B

`R_(1) = 6 Omega, R_(2) =15 Omega`

C

`R_(1) = 1.5 Omega, R_(2)` = any finite value

D

`R_(1) = 3 Omega, R_(2) =` any finite value

Text Solution

Verified by Experts

The correct Answer is:
D
The bridge ABCD is balanced if
`10/30 = R_(1)/9 = 3 Omega`
As no current flows in arm BD
`therefore R_(2)` = any finite value.
