In the given circuit, the potential difference between the points B and D is zero

The unknown resistance (X) is

A

`4 Omega`

B

`20 Omega`

C

`10 Omega`

D

`5 Omega`

Text Solution

Verified by Experts

The correct Answer is:
D
This is a balanced wheatstone's network.
`therefore (1)/(40)+(1)/(40)=(2)/(40) " " therefore R_(AD)=20 Omega`
`therefore (16)/(4)=(20)/(x) " " therefore x= 5 Omega`
