Consider the circuit shown in Fig. 7.22. This circuit is the same as that analyzed in Example 7.8, except that a constant forcing function is present. The circuit parameters are the same as those used in Example 7.8:
C=0.04 F i_{L}(0)=4 \mathrm{~A}
L=1 H v_{C}(0)=-4 \mathrm{~V}
R=6 Ω
We want to find an expression for v_{C}(t) for t > 0.
