6. In the circuit shown below the switch 5, is closed at $t = 0$. Find the initial and final currents through the inductor and the time constant for the circuit for $t > 0$. 7. In the circuit shown below the switch is open prior to $t = 0$ and so is operating in the steady-state condition. At $t = 0$, the switch is closed. Find expressions for the current $i(t)$ for $t < 0$ and for $t \ge 0$. 8. In the circuit shown below the switch changes position from 'A' to 'B' at $t = 0$. Assume steady-state conditions for $t < 0$. Determine the voltage (with polarity) across the inductor for the circuit shown below, before and after the switch changes its position.
