Electrical Engineering For the final problem, consider the following circuit diagram: 12 Q 30 V Vx 60 Q 2"Vx B 6) For this circuit, please find and draw: a. The Thevenin equivalent circuit between A and B, using external excitation to find R. b. The Norton cquivalent circuit berween A and B. c. Review section 3-8 from the text. What value load resistor connected between A and B would yield maximum power transfer? How much power woukd this be?

For the following circuit, obtain the table of voltages in the capacitor, for when the power supply has a value of 170 V pp, and the frequency of the source varies from 100 Hz to 1000 Hz in 100 Hz intervals. On a graph represent the voltage/frequency values and find a general conclusion based on the results obtained.
