  in D&S Repeat P12.4-1, parts a, b, d, and e

  (base) apparent power.
 
  Note errata on 2-16.

9/19 9/22 9/27   Read in D&S Ch 12 Sec. 9, 10, 11
  or Read in A&S Ch 12 Sec. 10, 11
 
  Do in D&S P12.9-1, P12.9-5, DP12-3
 
  Hint for P12.9-1 and DP12-3: 1 HP = 745.7 W
 
  Note errata on P12.9-1, and DP12-3.

9/15 9/19 9/20   Read in D&S Ch 12 Sec 5, 6, 7, 8
  or Read in A&S Ch 12 Sec 4, 5, 6, 7
  Do in D&S P12.5-1, P12.6-1, P12.8-6
  Note: See errata on P12.8-6.
7

9/12 9/15 9/16   Read in D&S Ch 12 Sec 1-4.
  or in A&S Ch 12 Sec. 1-3.
 
  Do in D&S P12.3-1, P12.4-1, P12.4-3
 
  Do these additional parts to P12.4-1:
  e.) Find phasor line voltages Vab, Vbc, and Vca.
  f.) Show the above phasor line voltages on a
       phasor diagram using solid lines. On the
       same phasor diagram show phasor phase
       voltages Va, Vb, and Vc using dashed lines
 
  Note: Make phasor diagrams large enough and
  make them accurate. Also, parts (c) and (f)
  of P12.4-1 require separate axes units (amps
  vs. volts) and thus cannot be combined into one
  diagram.
 
  Note: In chapter 12 Dorf & Svoboda's text
  uses power systems type phasors. The text is
  also carful to show units of "V rms" or "I rms"
  to indicate the use of power systems type
  phasors.

Note 1) Homework solutions are usually available one or two class periods after the due date. Click the "returned date" on this page to access the solutions. If the "Returned" date 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 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.

Note 3) 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.
