A ring is made of a wire having a resistance $\displaystyle \mathrm{R}_0=12 \Omega$. Find the points A and B, as shown in the figure, at which a current carrying conductor should be connected so that the resistance R of the sub circuit between these points is equal to $\displaystyle 8 / 3 \Omega$.
Official answer
(2)
$\displaystyle \frac{l_1}{l_2}=\frac{1}{2}$
