ELEC3105 WINTER 2020


  • The Instructor is Prof. Barry Syrett in Room 4150 Mackenzie
  • Office hours: 30 minutes after class


  • The University and our Department is scrambling to determine how we will hendle the last 2 1/2
    weeks of term. All face to face interaction with students has been cancelled -- no lectures, labs, exams etc.
    Accordingly midterm 2 has been cancelled. We do not know at this time how to deal with the final exams, and how
    course term/final exam grades will be redistributed. It is certain that final exams will not be held as usual.
    To complete ELEC 3105, you will do the following:
    1) I will give the final lectures online --I do not know if Wednesday's lecture will be given at the usual time.
    I will let you know by CULearn when you can view the lecture. I finished the lecture on transformers last Friday.
    Remaining materal is analysis of three-phase circuits, and some material on DC and AC motors. The material on motors
    will not be examined in any case. In the meantime you can read the lecture material on the course website.
    2) The TAs have made a video performing Lab 5 and provided the data for you to analyze and complete a lab report
    I sent you all a notice of this on CULearn yesterday. All sections must do the lab this week at your convenience
    but the lab report must ne submitted online to the TA Milan PAtel by midnight March 20.
    3) The solutions for PA 6 have been posted on CULearn. The TA Joseph Hyland will make a video of
    a PA session and post online. Solutions to PA 7 will follow. A short question for each PA session will
    be posted on CULearn for you to submit an answer for the remaining bonus martk.

    Consult this website periodically for any more news.

    Student Engagement

    It is alarming that attendance at engineering lectures is poor. Many studies have shown
    that examination performance in a course is highly correlated with student engagement.
    One measure of student engagement is attendance at lectures. Since most courses at
    university nowadays provide online lecture notes (including this one), lecture time can be used
    for true interaction with students to their immense benefit. I am running this course to enhance
    engagement amd I strongly encourage you to take advantage of this. You increase your engagement by:

    1) Attempting the problems of the PA session yourself before attending the session and using the
    PA session to enhance your understanding (not just copying the solution which basically does
    nothing for you -- I guarantee you will not see the same problems on an exam)

    2) Reading the lecture notes before the lecture and reading supplemental material in the
    textbook to improve understanding. There are many more examples in the textbook.

    3) Attending lectures where the important and often difficult concepts are explained and applied
    to examples, and asking questions in the lecture.

    If you do these in this course ( or any other course) you will maximize your chance to do well
    in the course. A high WDF (Withdrawn, D grade or F grade) is common in this course
    If you choose not to do the above it is very likely you will be part of this statistic.


    Prerequisite course PHYS104 or PHYS1002 includes discussion of electric and magnetic fields at an introductory level.
    Intermediate level Electromagnetics covered in this course requires vector calculus to analyze and describe these fields.
    The course requires successful completion of MATH 2004 which in turn required MATH 1005 (or MATH2007) and MATH1104 (or MATH1107).
    You are expected to understand vectors and vector operations such as finding a unit vector, calculate scalar cross-product and vector cross-product.
    You are expected to be able to integrate over lines, surfaces and volumes in rectangular,cylindrical and spherical coordinates.
    You are also expected to be able to differentiate functions in any of these coordinate systems, since these are required to
    calculate gradient, divergence, and curl operations.
    The course will review the coordinate systems, as well as gradient , divergence and curl.
    The course will have detailed discussion on setup of the required integrals to evaluate the electric fields due to charge distributions
    The course will have detailed discussion on setup of the required integrals to evaluate the magnetic fields due to current distributions
    However there is not time to review the math that was taught in the above prerequiste math courses to solve the integrals.
    You are expected to be able to solve simple integrals and to use integral tables to evaluate more complicated ones.
    If your math skills in the mentioned areas are weak you should review them in the first month of the course.

    Lab Information

    Wait for the TA before starting the labs

    Labs 1 and 2 will be done by individual students until all computer stations
    are occupied. There will only need to be one or two stations where students
    need to double up as a group in a few lab sections.

    Since Labs 1 and 2 are done on the computer, the reports can be done
    during the Lab using Word and submitted at the end of the end of the lab
    There may be time during the lab to print the report on the printer in the lab.

  • Correction to lab1: 8. Problem 4, in the figure it is shown that "(Teflon: 0V)" which
    gives the wrong impression of assigning value of 0V to Teflon. Authors probably meant
    that Teflon has no excitation value and it is a dielectric. Assigning 0V to Teflon messes
    the Ansys simulation.

  • Instructions for Lab 1 and Lab 2 have been updated to new version of ANSYS software
  • Prelab 1 has also changed
