1. Based on the results of Tables 10.1, 10.2 and 10.3, can superpodtion be applied successfully to
voltage, cument and power levels in a DC ckcuit?
2. Ifone of the sources in Figure 10.1 had been insered with the opposite polacity, would there be a
significant change in the resulting voltage a node A? Could both the magnitude and polarity change?
3. If both of the sources in Figure 10.1 had been inserted with he opposite polarity, would there be a
significant change in the resulting voltage a node A? Could both the magnitude and polarity change?
4. Why is it important to note the polarities of the measured veltages and currents?

Specify the truth table of an octal-to-binary priority decoder. Include a V output to indicate that at
least one of the inputs is present. The entry with the highest subscript will have priority. What value
will the four outputs have if inputs D5 and D3 are 1 at the same time?
