Unformatted text preview: 1 1 Test #1 Sept. 21, 2010, Tuesday, 6:30 - 7:30 PM, PHYS 112 No calculator, no electronic device and no formula sheet Tables 12.1 and 12.2 will be handed out with the test. Material covered: Up to and include Lecture 11 (This Friday’s lecture) Ch. 12, 13 and 14 HW # 1, 2, 3 and 4 (and 5?) A seating chart will be posted in 202 Help Room (MSEE 180) and on my office door (MSEE 262) by 9/21/2010 noon. You have to sit in the assigned seat only. Pictures will be taken during the test. Bring PU ID (Photo ID) 8 to 12 MC questions and 1 to 2 WO questions. Turn in the scantron sheet and the test packet. 2 Summary of Lecture #9 9/13/2010 • Thevenin and Norton equivalents • Superposition • Examples • Switching RLC circuits • Construct the s-domain circuit for t > 0 . • Account for initial conditions at t = 0- . • Determine V c (s), I L (s), then v C (t), i L (t) etc. 3 C v c (t) i c (t) +- v c (0- ) Cv c (0- ) I c (s) V c (s) +- I c (s) V c (s) +- +- Cs 1 v c (0- ) s i L (t) v L (t) +- L i L (0- ) I L (s) V L (s) +- Ls i L (0- ) s +- Ls I L (s) V L (s) +- Li L (0- ) Cs 1 Circuit elements having non-zero initial conditions in time and frequency domains Current source in parallel Voltage source in series 4 Thevenin Theorem for active circuits Almost any two-terminal, linear circuit consisting of passive elements, independent and depend sources is equivalent to a two-terminal circuit consisting of an impedance Z th in series with an independent voltage source V oc .
