1. Do the polarities of the sources in Figure 13.3.1 matter as to the resulting voltages? Will the magnitudes of the voltages be the same if one or both sources have an inverted polarity?
2. In both circuits of this exercise the negative terminals of the sources are connected to ground. Is this a requirement for nodal analysis? What would happen to the node voltages if the positions of E1 and R1 in Figure 13.3.1 were swapped?
3. The circuits of Figures 13.3.1 and 13.3.2 had been analyzed previously in the Superposition Theorem exercise. How do the results of this exercise compare to the earlier results? Should the resulting currents and voltages be identical? If not, what sort of things might affect the outcome?
