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).

Question

 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).
