When a coil is connected across a $\displaystyle 20$ V dc supply, it draws a current of $\displaystyle 5$ A. When it is connected across $\displaystyle 20$ V, $\displaystyle 50$ Hz ac supply, it draws a current of $\displaystyle 4$ A. The self inductance of the coil is $\displaystyle \_\_\_\_$ mH. (Take $\displaystyle \pi=3$ )
