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