Figure 1-6.—Circuit with parallel linear impedances.
Positive or negative voltage values can be used to plot the voltage-current graph. Figure 1-7 shows
an example of this situation. First, the voltage versus current is plotted with the battery polarity as shown
in view (A). Then the battery polarity is reversed and the remaining voltage versus current points are
plotted. As a result, the line shown in view (C) is obtained.
