In the given circuit at \( t=0 \), switch \( S \) is closed.
The energy stored in the inductor at any instant \( t(0t\infty) \) will be
(1) \( \frac{1}{2}\left[5-5 e^{-(1000 / 3) t}\right]^{2} \mathrm{~mJ} \) (2) \( \frac{125}{2}\left[1-e^{-(1000 / 3) t}\right]^{2} \mathrm{~mJ} \)
(3) \( \frac{25}{2}\left[1-e^{-(1000 / 3) t}\right]^{2} \mathrm{~mJ} \) (4) \( \frac{5}{2}\left[1-e^{-(1000 / 3) t}\right]^{2} \mathrm{~mJ} \)
