For what value of unknown resistance X, ...

For what value of unknown resistance `X`, the potential difference between `B` and `D` will be zero in the circuit shown in the figure ?

A

`4 Omega`

B

`6 Omega`

C

`2 Omega`

D

`5 Omega`

Text Solution

Verified by Experts

The correct Answer is:
B
`12/(x + 6) = (1//2)/(1//2)`
`rArr x + 6 = 12 rArr x = 6`
