12/08
at
5 PM
12/09 		  Read 12.10, 12.11
  Do 12.66 and P11.6-6 from another textbook
  (Your Web brouser must be logged in to
  courses @ dordt. for the above link to work.)
  Note errata on pages 534–535.
  Note errata on Problem 12.66.
  Hint on P11.6-6: The power angle is defined
  as (θv – θi) but θv = 0 due to the location
  of the given reference node. Then what is θi ?
 
  On Wednesday, 12/08 there will be a box labeled
  "EGR 220 Homework" near Prof. De Boer's office
  door. Drop your homework in the box by 5 PM
  Wednesday, 12/08 for final grading.
 
  This problem set will be graded and ready for
  pickup by 5 PM Thursday, 12/9. Pick your
  homework up from Prof. De Boer's plastic bin
  near the engineering pod door.
38

12/03 12/06
12/08
12/09 		  Read 12.7
  Do 12.33, 12.36
 
  Note on Problem 12.36: The given voltage is
  the voltage at the load. The source voltage
  needs to be a little greater to make up for
  loss in the transmission line. (It is a
  common practice to run generators and voltage
  sources at a somewhat higher voltage than
  nominal in order that the load may be supplied
  with the nominal voltage.)
 
  Note errata on Problem 12.36 part (c).
 
  This problem set will be graded and ready for
  pickup by 5 PM Thursday, 12/9. Pick your
  homework up from Prof. De Boer's plastic bin
  near the engineering pod door.

12/01 12/03
12/06
12/08 		  Read 12.1, 12.2, 12.3, 12.4,
  Note Table 12.1, pg 518.

  note especially Eq. 2.57 on page 55. See also
  pages 392 and 393 and Eq. 9.69.
  Note errata on Figure 12.15.
 
  Do 12.5, 12.7, 12.10
  Note errata on the answer to Problem 12.5.
  Note errata on Problem 12.7.
 
  Note 1.) "Determine the current," means "find
  the RMS value of the current," which is what
  an AC ammeter does. There is no angle in the
  answer. Only give phasors as answers when
  phasors are requested.
  Note 2.) All voltages and currents given
  in Chapter 12 are RMS unless otherwise noted.
  Note 3.) Use the phasor transform when
  possible. It makes these problems easier.

Note 1) Homework must be ready for peer grading and discussion in class on the first listed due date. It must be turned in for a final grade on the second listed due date. Peer grading will be 1/5 (20%) of the homework grade.

Note 2) If the "Returned" date is a link, then solutions are available by clicking the link. If you click the link and get a login screen, use your usual courses@dordt login. Then use the back icon (or alt-left-arrow on the keyboard) twice to get back to the link and click it again. The link only works if you are logged into course@dordt.

Note 3) 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.

Note 4) If you are having difficulty reading the latest version of this page it may have to do with your browser's cached memory. Read this note on cached pages to solve the problem.

Note 5) Assingend work in the lists above are above are "Problems" or "Comprehensive Problems" found at the end of each chapter. Your textbook also includes "Practice Problems" which are embedded within the chapters and "Review Questions" at the end of each chapter. These are not assigned, but you should attempt them. Complete answers to "Practice Problems" are available from the textbook's publisher. Answers to odd numbered "Problems" can be found in the back of the textbook.
