A $630$ mH inductor whose windings have a $3\mathrm{.}6$ resistance is connected across a $15$ V battery with a $1\mathrm{.}8$ internal resistance. After a very long time, how much energy is stored in the inductor?

$5\mathrm{.}1{10}^{-1}J$

$1\mathrm{.}5{10}^{1}J$

$1\mathrm{.}4{10}^{0}J$

$6\mathrm{.}8{10}^{0}J$

$2\mathrm{.}4{10}^{0}J$
