QJEEM23Phb4eb: JEE Main 2023 Physics - Class 12 JEEM23Phb4eb Solution: If the potential difference between and is zero, the value of…

The circuit is a Wheatstone bridge, so

${{{{6 \times 3} \over {6 + 3}}} \over {{{x \times 1} \over {x + 1}}}} = {{1 + 2} \over x}$

$\Rightarrow {{2(x + 1)} \over x} = {3 \over x}$

$\Rightarrow x = {1 \over 2}$

So $n = 2$
