Accepted Answer

$$ 	ext { The given circuit can be drawn as: } $$
From the figure, we can see that this is a balanced Wheatstone bridge.
$$ \begin{array}{ll} 	herefore & \frac{1}{\mathrm{R}}=\frac{1}{15}+\frac{1}{30}=\frac{3}{30}=\frac{1}{10} \ 	herefore & \mathrm{R}=10 \Omega \ 	herefore & \mathrm{I}=\frac{5}{10} \ & \ & =0.5 \mathrm{~A} \end{array} $$
