1. Based on the results of Tables 10.5.1, 10.5.2 and 10.5.3, can superposition be applied successfully to voltage, current and power levels in a DC circuit?

2. If one of the sources in Figure 10.3.1 had been inserted with the opposite polarity, would there be a significant change in the resulting voltage at node A? Could both the magnitude and polarity change?

3. If both of the sources in Figure 10.3.1 had been inserted with the opposite polarity, would there be a significant change in the resulting voltage at node A? Could both the magnitude and polarity change?

4. Why is it important to note the polarities of the measured voltages and currents?
