EECS 210_________________________PROBLEM SET #8________________________Winter 2001

ASSIGNED: March 16, 2001. Read: Sects. 9.6-9.12 (skip Sect. 9.10) of text. Start Chap. 10 (power).
DUE DATE: March 23, 2001. In Lab Book: Read Unit #5, Lab Lecture #5 and Lab Experiment #5.
THIS WEEK: Phasor analysis of linear circuits in the sinusoidal steady-state.
1. Text #9.10. Simple phasor circuit. Note the inductor and capacitor impedances partially cancel.
2. Text #9.16. The admittance "seen" by the (source+150 Ohms) should be purely real (why?).
3. Text #9.17. What impedance should be "seen" by the source? Watch the "sin" and "mA" in io.
You will get a quadratic equation for frequency, but only one root will be positive.
4. Text #9.19. Just combining in series and parallel, but now using impedances and admittances.
5. Text #9.26. Compare to #9.25: note equating admittances instead of impedances makes easier.
6. Text #9.31. Voltage divider using impedances and phasors. Watch signs: phase is NOT zero.
7. Text #9.37. Thevenin equivalent using impedances and phasors. VTH=350+j0; RTH=100(1+j).
8. Text #9.49. 1 Node eqn. using impedances and phasors. Watch the "sin" in vg2. Vo=12+j0.
Q: What is the difference between Bill Clinton, Dan Quayle, and Jane Fonda?
A: Only Jane Fonda went to Vietnam in the 1960s (an old political joke).
