For $t<0$, the circuit shown in Eigure P4.68 is in DC steady-state. The switch is closed at $t=0$. Determine the current $i_L$ through the inductor and the voltage $v_C$ across the capacitor for $t>0$. Assume $R=3 \mathrm{k} \Omega, R_S=600 \Omega, V_S=2 \mathrm{~V}, C=2$ mF , and $L=1 \mathrm{mH}$.
