Problem 6-4. For the circuit shown in figure P6-4, find $v_L\left(0^{-}\right),v_L\left(0^{+}\right),v_L(\infty )$, $i_L\left(0^{-}\right),i_L\left(0^{+}\right),i_L(\infty ),v_L(t)$ for $t\ge 0^{+}$and $i_L(t)$ for $t\ge 0^{+}$. Determine the initial and final energy stored in the inductor. The switch has been in its starting position for a long time before moving at the time indicated. Figure P6-4. Switched RL circuit.
