Work only on one side of the paper. Use this sheet as your cover sheet, placed on top of your work and stapled in the top left-hand corner. Number the problems at the top of the page, in the center of the sheet. Do neat work. Underline your answers. Show how you got your equations. Be sure to show how you got your answers. Each problem counts 10%, except problem (10.55) counts 20%. This is a minimum problem set. You will probably want to work other problems to refine your uderstanding of A.C. circuit analysis. Basic Concepts: Voltage Division Ans: vo(t) = 17.14cos(200t) V Basic Concepts: Impedance Ans: is(t) = 460.7cos(2000t + 52.6o) mA Basic Concepts: Current Division Ans: vx(t) = 50cos(100t 50o) V Basic Concepts: Impedance (calculator exercise) Ans: Zin = (51.1 + j9.88) ( Basic Concepts: Impedance Ans: ZT = (19 j5) (, I = 1.53(104.7 A Nodal Analysis Ans: V1 = 28.9(135.4o V; V2 = 49.18(124.1o V Nodal Analysis Ans: Io = 9.25(-162.1 A Mesh Analysis Ans: Io = 2.18(61.4o A Mesh Analysis Ans: Io = 3.35(174.3 A Thevenin and Norton In finding the Norton circuit, you are to do so by finding the open-circuit voltage and short-circuit Current. Draw both the Thevenin and Norton equivalent circuits.
