12/05 12/12
  		12/13   Read Chapter 6
  Do the computer project (described on the main
  courses@dordt page for this course).

  		12/10#   Read 4.7, 4.8
  Do 4.5, 4.6
 
  Note errata on pages 115 and 116.

11/16 11/30
  		12/03#   Read 4.1 through 4.6

8

11/02 11/07
  		11/13#   Read 3.4 through 3.12
  Do 3.4 and add part (d):
        (d) By inspection of the graph from part (c),
        estimate the maximum power angle allowed
        if the relationship between the power
        generated and the power angle is to act
        approximately linearly. Also, what is the
        pull-out angle?
       
        Hint for part (a): Consider what cos(delta + theta)
        represents in Figure 3.8. Then use the Trig. ID
        cos(delta + theta) = cos(delta)cos(theta) – sin(delta)sin(theta).
        Also note text Equation 3.30.
       
  Also do 3.6
 
  Note: After class on Monday, 11/05, Prof.
  De Boer moved 3.7 and 3.8 to the next problem
  set because we have not covered those topics in
  class yet.

  Do 3.13, 3.16.
  Note that an "impedance diagram" is a
  conventional schematic of a Y-equivalent
  per-phase model of the system. The quantiites
  labeled may be in conventional units or in
  per-unit measures, but usually are not mixed.
 
  As per our discussion in class on Wednesday,
  10/17, the due date for this assignment was
  changed from 10/17 to 10/22.

  		9/07#   Read Chapter 1
  Do 1.1, 1.2, 1.3
  On 8/31 the due date was changed from 9/3
  to 9/5 due to computer problems on campus.
  On 4/5 the reading assignment explicitly shown.

Note 1) If a "#" follows the "returned" date, then the solution key is posted on the cork board across the hall from room S233.

Note 2) Problems sets shown above with no "assigned" date are tentative. More problems might be added, expected due dates might change, but problems shown will eventually be assigned.
