Course Description

Catalog Description: Application of fundamental concepts of electrical science in linear circuit analysis; mathematical models of electric components and circuits.

Credits: 3

Prerequisites: MATH 315 with a C or better or concurrent enrollment; PHYSICS 202 with a C or better.

Important: Link to “official” course syllabus (including tentative schedule).  Some of the material form the syllabus is duplicated below.  If there is any contradiction between the information below and the syllabus, the syllabus has precedence.

Textbook/Technologies

Required: The "Mastering" version of Electric Circuits, 12th ed., J. W. Nilsson & S. A. Riedel, Prentice Hall, 2022.  ISBN: 9780137648375 (for hardcopy, but don't buy unless you want the hardcopy!).
Electronic version of textbook is included automatically because of the course fees you pay for this course.  See “Homework 0” for additional information.

Required: iClicker Student.  This is not a textbook, but a “rapid response” technology that will allow you to participate in interactive polls during lecture.  You will respond to polls via your phone, using a browser, or a physical remote.  If you do not have a physical remote and don’t want to purchase one, you will need to purchase an iClicker Student subscription (costs start at $15.99 for six months).  Once you have done that, if you want to use your phone to respond, you will need to install the iClicker Student app.  You may also respond via a browser, but you will likely find that more cumbersome than responding via the app on your phone.  If you’ve previously purchased an iClicker physical remote, that should suffice, but you will have to remember to always bring that to class.  If you have purchased a physical remote very recently or do so now, that will come with five years of digital access so you would have the option to respond with the physical remote, your phone, or via a browser. Please visit the iClicker website for purchasing options (direct link to pricing page).  Importantly, when you register/create an account, please be sure to use your WSU email address.

Recommended: There will be various points throughout the course where MATLAB will be mentioned.  MATLAB is a very powerful tool that can make many problems much easier to solve than they would be otherwise.  You will be doing yourself a favor if you download MATLAB and become comfortable with some of its functionality.  MATLAB is free to all WSU students.  Go here for further information about downloading MATLAB.  Note that MATLAB is very large and can, depending on your access to the Internet, take a significant time to download and install.  Installing this is definitely not something you want to do the night before you really need to use it.

Schedule

NOTE: Unlike the tentative schedule available in the syllabus, the schedule shown below reflects what actually happened on past dates.  Any indication of activities on future dates remains tentative.

Quizzes

The clicker “quiz” material is embedded in the lecture notes.  Please refer to the PowerPoint slide decks for questions and answers.

Grading

The metrics that make up your final numeric score:

Metric Value
Test #1 19%
Test #2 19%
Test #3 19%
Final Exam 21%
Homework 14%
Clickers/Quizzes/Attendance 8%

Mapping of numeric score to final grade:

Score Grade
≥92
≥88 and < 92 A-
≥84 and < 88 B+
≥78 and < 84
≥74 and < 78 B-
≥70 and < 74 C+
≥61 and < 70
≥57 and < 61 C-
≥50 and < 57
< 50

Note 1:  There is no possibility for extra-credit work.  Thus, please monitor your own performance and plan accordingly.

Note 2:  Your numeric score will be calculate to one decimal place.  There will be no rounding up and the cut-offs shown above are as stated.  Thus, for example, if you have a numeric score of 77.9, your grade will be a B-.

Homework:  Assignments carry equal weight despite not necessarily being of equal difficulty.  The two lowest homework scores will be dropped.  Homework must be submitted by the posted due-date.  Late homework will not be accepted.

Quizzes/Clicker Questions/Attendance:  In-class “quizzes” will be administered regularly in the form of clicker questions.  All quizzes carry equal weight.  The three lowest scores will be dropped.  Missed quizzes cannot be made up.  Partial credit will be awarded for attendance (but you must respond to at least question to be counted as present).

Miscellaneous

Please consider reading this relatively short article by Carol Dweck that has nothing to do directly with the course but may have quite a bit to do with your success not only in this class but in also your future studies.  (The title is awful, so ignore.  The content of the article is the important thing.)  Alternatively, or in addition, the “Introduction to MasteringEngineering” has a section entitled “Mastering Your Mindset” with several videos that nicely summarizes much of Prof. Dweck’s research.

Students Needing Accommodations

Reasonable accommodations are available for students with a documented disability.  If you have a disability and need accommodations to fully participate in this class, please either visit or call the Access Center in the Washington Building, RM 217 (phone 509-335-3417; accesscenter.wsu.edu, Access.Center@wsu.edu) to schedule an appointment with an Access Advisor.  All accommodations MUST be approved through the Access Center.  For more information contact a Disability Specialist on your home campus.

Academic Integrity

WSU’s Official Academic Integrity Statement:

“Academic integrity is the cornerstone of higher education.  As such, all members of the university community share responsibility for maintaining and promoting the principles of integrity in all activities, including academic integrity and honest scholarship.  Academic integrity will be strongly enforced in this course.  Students who violate WSU’s Academic Integrity Policy (identified in Washington Administrative Code (WAC) 504-26-010(3) and -404) will receive fail the course, will not have the option to withdraw from the course pending an appeal, and will be reported to the Office of Student Conduct.

“Cheating includes, but is not limited to, plagiarism and unauthorized collaboration as defined in the Standards of Conduct for Students, WAC 504-26-010(3).  You need to read and understand all of the definitions of cheating: http://app.leg.wa.gov/WAC/default.aspx?cite=504-26-010.  If you have any questions about what is and is not allowed in this course, you should ask course instructors before proceeding.

“If you wish to appeal a faculty member’s decision relating to academic integrity, please use the form available at conduct.wsu.edu.”

Additional information concerning academic integrity for this class can be found in the syllabus.

Safety and Emergency Notification

WSU’s Official Safety and Emergency Notification Statement:

“Classroom and campus safety are of paramount importance at Washington State University, and are the shared responsibility of the entire campus population.&ldquoll WSU urges students to follow the ‘Alert, Assess, Act,’ protocol for all types of emergencies and the ‘Run, Hide, Fight’ response for an active shooter incident.  Remain ALERT (through direct observation or emergency notification), ASSESS your specific situation, and ACT in the most appropriate way to assure your own safety (and the safety of others if you are able). Please sign up for emergency alerts on your account at MyWSU.  For more information on this subject, campus safety, and related topics, please view the FBI’s Run, Hide, Fight video and visit the WSU safety portal.”

Lauren’s Promise

I will listen and believe you if someone is threatening you. Lauren McCluskey, a 21-year-old honors student athlete, was murdered on Oct. 22, 2018, on the University of Utah campus by a man she briefly dated.  We must all take actions to ensure that this never happens again.

If you are in immediate danger, call 911.

If you are experiencing sexual assault, domestic violence, and stalking, please report it to me and I will connect you to resources or call Alternatives to Violence of the Palouse at 877-334-2887 (24-hour crisis hotline).

Any form of sexual harassment or violence will not be excused or tolerated at Washington State University.  WSU has instituted procedures to respond to violations of these laws and standards, programs aimed at the prevention of such conduct, and intervention on behalf of the victims.

WSU Police officers will treat victims of sexual assault, domestic violence, and stalking with respect and dignity.  Confidentiality is of the utmost importance and WSU Police will assist by providing resources to victims.  In addition to its law enforcement efforts regarding sexual assault, domestic violence and stalking, WSU Police refer victims to the appropriate university and/or local community counseling and other resources devoted to assisting victims.

Advocates help survivors determine their own needs in regards to their physical and emotional health, reporting options, and academic concerns.  They connect survivors to campus and community services, and provide accompaniment to important appointments (court, hospital, and police) and support throughout the process.  WSUPD can also connect you with advocacy services, if desired.  The local advocacy group is Alternatives to Violence of the Palouse, whose services are free, immediate, and confidential.

Other confidential resources include WSU Counseling and Psychological Services.  If you would like to speak with a counselor after business hours, WSUPD can contact the on-call counselor and have them call you directly or a crisis telephone number is provided.  Information shared with the counselor will not be provided to WSUPD without expressed permission from you.

WSU Counseling and Psychological Services 509-335-2159 (crisis services line).
