The switch in the circuit shown in FIGURE Q2 has been closed for a long time. At t = 0 the switch is opened. i. With the switch closed, determine the inductor's initial current, i(0) and with the switch opened, determine the inductor's final current, i(∞) and the time constant. ii. Evaluate whether the circuit is a source - free or step response circuit. Hence, determine the inductor's current, i(t) for t > 0 iii. Discuss how the values of the voltage source and resistors in the circuit, affect the inductor's current, i(t).
