A $24\mathrm{.}0-$V battery is connected in series with a resistor and an inductor, with $R=4\mathrm{.}00$ and $L=7\mathrm{.}60H,$ respectively.

$($a$)$ Find the energy stored in the inductor when the current reaches its maximum value.

$J^J$

$($b$)$ Find the energy stored in the inductor at an instant that is a time interval of one time constant after the switch is closed.
