An inductor stores $\displaystyle 16$ J of magnetic field energy and dissipates $\displaystyle 32$ W of thermal energy due to its resistance when an a.c. current of $\displaystyle 2$ A (rms) and frequency $\displaystyle 50$ Hz flows through it. The ratio of inductive reactance to its resistance is $\displaystyle \_\_\_\_$. $\displaystyle (\pi=3.14)$
