List of Homework Problems and Tutorial Problems
How Does the Course Work? Each week, look on the Moodle site to find the lecture videos that you should watch before the Tuesday class so that you are prepared to solve problems. In the Tuesday class I will present a brief summary of the weeks lectures. Then I will ask you to solve some problems for the remainder of the lecture time. In the Thursday class I will give you some Workshop problems to solve. You will solve the problems during the class time and submit your solution to the Moodle web site, and it will be graded by the Teaching Assistant. Each week there are tutorial problems to solve during the tutorial session, and the TA will help you to solve these problems. Each week there are homework problems to solve, but you dont hand in the homework problems. I will put solutions to the homework problems on the Moodle site.
Learning Objectives for ELEC The broad Objective of the course is to be able to solve any electric circuit systematically, by writing linear equations and solving them. No guessing or tricks are needed! 1.Apply electric circuit l aws to write equations to determine the voltages and currents in an electric circuit. 2.Solve circuits with DC sources and resistors efficiently using node equations and mesh equations. 3.Solve circuits with dependent sources. 4.Solve circuits with operational amplifiers. 5.Apply source transformation principles to derive equivalent circuit models. 6.Determine transient voltages and currents in circuits made up of DC sources, resistors, inductors, capacitors and switches. 7.Solve AC circuits efficiently using complex numbers, phasors and impedance, using mesh analysis, node analysis and source transformations. 8.Use laboratory instruments to measure voltages and currents in circuits with DC sources, with switches, and with AC sources.
Grading scheme Tutorial workshops: 20 Laboratory: 20 Mid-term test #1 10 Thursday February 25 Mid-term test #2 10 Thursday April 1 Final Examination 40
Total 100
Administrative Rules 1.The mid-term tests will take place on Thursday February 25 and Thursday April 1. 2.There are no make-up mid-term tests. If you miss a mid-term test for any reason your final exam will be worth more marks to make up the difference. 3.If your final exam grade is better than your mid-term test grade, the mid-term will be discarded and the final exam will count for more marks. 4.You must have a grade of at least 50% in the laboratory in the course. If your lab grade is less than 50%, you will receive the grade R for the course, meaning that you must repeat the course. 5.Students who are repeating the course must also repeat the laboratory. 6.Each tutorial workshop counts for 2 marks, to a maximum of 20 marks. I will take the best 10 of your workshop grades over the semester. 7.Note that you must earn an overall grade of C- or better in ELEC273 to use the course to satisfy the pre- requisite requirements for later courses.
Tutorial Problems
Each week there will be a tutorial on Zoom which lasts from 12:45 to 2:25. The tutorials are problem- solving sessions. You can find the problems that you will solve in each tutorial in the list on the Moodle site entitled Homework and Tutorial Problems. You should come prepared for the tutorial by watching the video lectures for the week. During the tutorial you will solve as many of the problems in the list as you can, and finish the list later. During the tutorial you can ask the Teaching Assistant (TA) for help with each problem. The tutorial problems are not handed in and solutions are not provided.
Homework Problems
Each week there will be homework problems to solve. Doing the homework problems helps to prepare you for the midterm tests and for the final exam. Homework problems are not submit or graded. The solutions to the homework problems will be posted on Moodle at the end of the week.
In Class: Practice Problems
Each week in the Tuesday Zoom class, I will present a brief summary of the video lectures for the week. Then I will give you practice problems to solve in class so that you can use the skills you learned in the video lectures. At the end of the class I will solve the problems. Practice problems are not handed in or graded.
In Class: Workshop Problems
Each week in the Thursday Zoom class, I will give you Workshop Problems to solve in class. You can ask for help in solving each problem. The class is a workshop and not a quiz! At the end of the class, scan your work into a pdf file and submit it on the Moodle web site. No late submissions are accepted. Your solution will be graded. Each workshop counts for 2 marks. There are 11 workshops in all and I will take the best 10 of your workshop grades.
Laboratory
ELEC273 has a laboratory consisting of four experiments. You must have a passing grade on the labs in order to pass the course.
The lab coordinator is Jorris Moreau and can be contacted at [email protected]
COLE for the Mid-Terms and Final Exam The mid-term exam and he final exam will be on line exam and will be written using the Universitys COLE system. COLE has a practice exam for you to try so that you can become familiar with the COLE system: You may use your Concordia credentials to log into the COLE exam site where you will find practice exams and can become familiar with your online exam environment. You can find information about COLE at: https://www.concordia.ca/online/exams/online-exams.html
Behavior
All individuals participating in courses are expected to be professional and constructive throughout
the course, including in their communications.
Concordia students are subject to the Code of Rights and Responsibilities, Undergraduate Calendar
Section 17.30.
Academic Code of Conduct
All Concordia University students must abide by the University's Academic Code of Conduct.
The code can be found in the Concordia University Undergraduate Calendar, Section 17.10. Any
suspected violation of the Code will be reported to the Dean for investigation. Penalties can be as
severe as dismissal from the University.
Item 16.a of the Academic Code of Conduct forbids plagiarism. If you copy another students
assignment or lab report you are guilty of plagiarism. You may NOT copy assignments from
students who took the course in a previous year, for example.
Item 16.b forbids you to provide material to another student when there is the possibility that he or
she may copy it. If you allow another student to copy your homework assignment or lab report, you
have behaved unethically and committed an offence. If you give another student your homework
assignments or lab reports from a course that you took before, and he copies them, then you have
committed an offence.
In the Faculty of Engineering and Computer Science, you are forbidden from consulting the work of
any current or former student.
Extraordinary Circumstances
In the event of extraordinary circumstances and pursuant to the Academic Regulations in the Undergraduate Calendar, the University may modify the delivery, content, structure, forum, location, and/or evaluation scheme. In the event of such extraordinary circumstances, students will be informed of the changes.
Graduate Attributes
You are enrolled in an engineering program that is accredited by Engineers Canada, and when you graduate
you will be eligible to become a registered professional engineer. To practice engineering and use the title
engineer you must be a member of a provincial licensing body such as the Order of Engineers of Quebec
or the Professional Engineers of Ontario.
Engineers Canada operates the Canadian Engineering Accreditation Board (CEAB). CEAB visits each
Canadian university offering an engineering program about every five years, to renew the accreditation of
the program. One of the criteria is the list of 12 graduate attributes, which are core skills that every engineer must possess. Each course in your engineering program has some of the graduate attributes
associated with it, and the competence of the class as a whole is assessed for those core skills. The
evaluation of the graduate attributes does not contribute to your grade in the course as an individual student.
Instead, the overall performance of the class is evaluated.
The graduate attributes for ELEC 273 are as follows:
KB – A Knowledge Base for Engineering PA – Problem Analysis
UET – Use of Engineering Tools
ITW – Individual and Team Work
The course teaches the fundamental skill of linear analysis, the cornerstone of a knowledge base for
engineering. Many other courses depend on the skills learned in ELEC 273. Linear analysis is the skill of
writing equations that govern the behavior of a linear system such as an electric circuit, and solving those
equations to determine the performance of the system. In this course, solving circuits systematically by writing equations based on KVL and KCL is the fundamental skill that you are trying to master.
Problem Analysis is the skill of understanding an engineering problem and then modelling the problem and
solving it. Modelling is often done by creating an equivalent circuit that captures the behavior of the
problem, and understanding the limits of the validity of the equivalent circuit. The problem is solved by
writing equations based on the equivalent circuit, and solving the equations using skills learned in
mathematics courses, or by using a computer program such as LTSpice to solve the circuit.
Engineering tools include mathematical tools such as solving linear equations, solving first and second order
differential equations, and using complex numbers and complex arithmetic. You calculator is an
engineering tool and skill at obtaining correct numerical answers is fundamental. The circuit analysis
program LTSpice is an engineering tool. The instruments in the laboratory, such as a digital voltmeter, an
oscilloscope and a signal generator, are engineering tools.
Engineers practice Individual and Team Work every day in the workplace. Engineering problems are solved
by a team of engineers. The problem is broken down into smaller sub-problems and each member of the team is assigned a sub-problem for his or her individual work. The team meets regularly and reviews
progress in each sub-problem and each team member contributes ideas to the solution of each sub-problem,
and also understands how the sub-problems fit together to make a complete system. Then team must
integrate all the individual solutions together to make a working system. In ELEC 273 you will work with a
lab partner as a team of two engineers to perform the lab experiments and analyze the data. However, in the
course you submit individual lab reports. In later courses when you work as a team, the team submits one
report giving the solution developed by the team as a whole.
Each of these graduate attributes will be assessed by your Professor and your Lab Demonstrator for the class
as a whole. The overall performance of each class over many course sections is used to determine changes
to the courses in our program to improve the students skills in these 12 important core competencies.
