The value of unknown resistance $(x)$ for which the potential difference between $B$ and $D$ will be zero in the arrangement shown, is :

Answer:

Solution:

In case of balanced Wheatstone Bridge $\frac{V _{A B}}{V _{A D}} = \frac{V _{BC}}{V _{C D}} \Rightarrow \frac{12}{6 + x} = \frac{0.5}{0.5} x = 6Ω$
