Question D.4: Assuming that i(0)= 10A , plot the zero-input response i(t)......

The circuit is the same as the one for Example 7.3, where we obtained the solution as

i(t)  =  10 e^{(-2/3)t}

For PSpice analysis, the schematic is in Fig. D.31, where the currentcontrolled source H1 has been wired to agree with the circuit in Fig. D.30. The voltage of H1 is 3 times the current through inductor L1. Therefore, for H1, we set GAIN = 3 and for the inductor L1, we set the initial condition IC = 10.  . Using the Analysis/Setup/Transient dialog box, we set Print Step = 0.25  s  and Final Time = 4 s  . After simulating the circuit, the output is taken as the inductor current i(t), which is plotted in Fig. D.32.
