  Do: Problems 8, 9, 10, 11
 
  Optional:
  Video lecture: The Passive Sign Convention
  Video lecture: Passive Sign Convention Examples
  Note: The passive sign convention is easy once you
  clearly understand it. However, there are lots of bad
  descriptions of it floating around on the internet.
  Stick with the IEE handout, the videos above, or ask in
  class rather than conslulting the internet on this matter.

3/21 3/24
3/26
3/31   Topics: Electric Energy, "Free Niagara,"
              AC Circuits
  Read: Sections 4, 5 and 6 (p 6 – 18)
  Do: Problems 5, 6, 7
 
  Optional: The Grid. (13 min. video)
  Optional: read about arc flash and watch
  When good transformers go bad,
  480 volt 3-phase Arc Flash Demonstration
  An arc-flash incident in 2008
  Detial on the above--the arc-blast.
  The point is that safety matters. Electric
  circuits can delever impresseive amounts of
  destructive energy when failures happen.

Note 1) Homework must be ready for peer grading and discussion at 10 AM (at the start of class) on the first listed due date. Peer grading will offer 4 points per peer grading event.

Note 2) Homework must be turned in for a final grade at 10 AM (at the start of class) on the second listed due date.

Note 3) Homework solutions are usually available within 24 hours after the due date. Click the "returned date" on this page to access the solutions. If the "Returned" date is not shown or is not a link (is black, not gold) then the solution is not yet posted. Check back later. If you click the link and get a login screen instead of the solutions, log in using your usual courses@dordt username and password. Then use the back icon (or alt-left-arrow on the keyboard) twice to get back to the link on this page and click the link again. The link only works when you are logged in to courses@dordt.

Note 4) 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 5) 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.
