Part A Assume that the switch in the circuit given below has been closed for a long time and the source current $A=9\mathrm{.}00mA.$

Calculate $iL(t)$ at the instant just after the switch opens.

The inductor current $i_L(O^{+})$just after the switch opens is $q,$ mA$.$

Part B Assume that the switch in the circuit given below has been closed for a long time and the source current $A=9\mathrm{.}00mA.$

$$

Calculate $i_L(t)$ at the instant just before the switch opens.

The inductor current $iL(0)$ just before the switch opens is $q,7$ mA $.$

Part C Assume that the switch in the circuit given below has been closed for a long time and the source current $A=9\mathrm{.}00mA.$

Calculate $iL(t)$ at the instant just after the switch opens.

The inductor current $($:$\frac{i}{0^{+}}$
