How to excel in this course

There are three important steps in learning a complex topic such as circuit analysis:
(1) reading about it,
(2) having it explained to you by a knowlegible person
(3) and doing it.

The Textbook

Introduction to Electric Circuits, 9th Edition, by Richard C. Dorf and James A. Svoboda, © 2014 by John Wiley & Sons, Inc.;  ISBN 978-1-118-47750-2
This is our textbook. Reading assignments are indicated in the schedule. No textbook is perfect, but ours is more than adequate and will serve you for this course and the one that follows, EE 3446. Although our homework is not taken from this textbook, it would be a grievous error to not obtain it and read the chapters as assigned. The reading gives you a preview of what will be discussed in the lectures and will greatly aid your understanding. Having read the material, you will be primed to gain the most understanding from the lectures and examples.


This is the second major step in understanding electric circuit analysis. Although much of the material for this course is available from the course web site, regular attendance is expected and will help you achieve success. Class interaction and peer bonding with other members of the class have been shown to be important factors in learning. Missing a class should be a rare occurrence such as an emergency and not a habit. (Cutting class in order to cram for an exam in another class is considered poor time management, rather than an emergency.) Accordingly, each hour of unexcused absence from lecture or lab will accrue as a half percentage point debit from your final grade. (Be sure to email me in advance, if possible, about the emergency you are facing that will require your absence.)

Attendance will be taken by your initialing your name on the class roll sheet located at the front of the classroom. It is your responsibility to do this. On days when you submit written work such as problem labs and exams, there will be no sign-up sheet. The existance (or lack) of the submitted work will indicate your presence (or absence).

If you must be engaged in a part-time or full-time job that regularly conflicts with our class schedule, you should seriously consider (a) enrolling in the other section (if there is one and there is still time to do that) or (b) dropping the course.


You will be expected to submit your solutions to selected circuit problems during the Laboratory sessions. These will be problems assigned at the beginning of the session; the instructors will help you if you need it. This will constitute 8% of your course grade.

Homework Submissions

This is the third major part of learning electric circuit analysis. Homework assignments will be found under the "Homework" button in the navigation panel (to the left of this page). After you have selected this button, you will be asked to log in as a user. This will be your standard UTA login with your UTA user ID and your current UTA password. Once you are logged in, select “See Problem List” to get a list of the homework problems. Work on the column for the assignment you need, i.e., HW01, HW02, etc. When you enter your answers, they will be immediately checked and you will be informed whether you got it right or not. When you get the problem correct, the data base records your results. Correct answers submitted before the due date get full credit regardless of how many attempts were made. (We record the number of attempts, but do not penalize for them.) We would prefer that you keep on trying until you get it right.

However, the homework does have a due date. Correct answers submitted after the due date will be assessed a penalty of 2% per day late for up to 25 days. After 25 days, there will be no further deductions, but a maximum score of 50% will be awarded for the correct answer for a problem. Avoid these penalties by seeking help from your instructor or your GTA, both of whom have regular office hours or will set up appointments if necessary. Bring your notes of attempts to solve the problems to the meeting with us.

Software Requirements


You will need a good quality scientific calculator. We recommend the TI-89, TI-nspire or the HP-50. The calculator you provide will need the capability of solving simultaneous linear equations with both real and complex coefficients. Since these capabilities will be required in most of the ensuing courses in Electrical Engineering, we recommend that you acquire the calculator now. Both exams and homework will call upon the capabilities of these calculators.


The two major examinations and the comprehensive final examination will be the old-fashioned paper,  pencil and calculator exercises.  Students will take these exams at the scheduled times in the classroom.

When solving exam problems, you are expected to document your work. A miraculously correct answer with no solution steps shown will not be credited. Successful professionals document their works. Always leave a solution trail. Then you may get some partial credit for even an erroneous answer if some of the steps are correct and logical.

When beginning a multiple-problem exam, take a moment to explore the exam looking for the problems that you understand best. Work those first. Do not struggle with a poorly understood problem when there are others you can readily solve. Cherry-picking the easiest problems first will maximize your test scores.

Adobe Acrobat Reader 11.0

This free program can be downloaded from http://get.adobe.com/reader/.

Downloading PSpice

You can obtain your own installable version of PSpice at this site. Those of you who have strict firewalls should download the installation file (about 27 Mbytes) and then install it from your desktop or another storage location. Note that this web site has pdf documentation on using PSpice.


Submitting PSpice Assignments

PSpice assignments will have deliverables consisting of the printouts of either the output file (text) or graphics from the probe application. The instructions will indicate which. In some cases, both will be required.

In all cases, your name must be clearly printed (by PSpice) on the document.

Skills and Knowledge You Will Acquire

    Fundamental electric circuit concepts such as Kirchhoff's voltage and current laws (KVL and KCL), Ohm's law and the Passive Sign Convention as applied to DC circuits as well as the phasor domain will be mastered to the extent that they can be used to solve linear circuit problems for both DC and steady-state AC applications.
    The Node Voltage and the Mesh Current frames of analysis will be used to develop the circuit models based on the foregoing concepts.
    Fundamental electric network theorems such as Thévenin's and Norton's theorems, the Maximum Power Transfer Theorem and the Superposition theorem will be developed as tools of understanding that will enable students to simplify and analyze complex electric circuits in order to effectively design useful engineering applications.
    The Ideal Operational Amplifier will be introduced as a multi-terminal device to develop fundamental electronic concepts such as the inverting amplifier, the non-inverting amplifier, the summing amplifier and several specialized applications.
    The fundamental physics of simple linear inductors and capacitors will be developed into circuit models capable of modeling the time-differential circuit equations, phasor domain relationships and energy storage issues. At the end of the course, the concept of mutual inductance as applied to electric circuit analysis and ideal transformers will also be introduced.
    Transient and step response of linear RL and RC circuits will be mastered.
    The concepts of real, reactive and complex power as well as the concept of lagging and leading power factor in the phasor domain will be mastered to the extent that single-phase power will be understood and students will be capable of analyzing and understanding the basic issues of simple AC power applications.
    Ideal transformers applied to phasor circuit analysis and complex power calculations for single-phase applications will be understood.
    Passive first and second order analog filters and active first order filters will be developed in order to introduce the concept of frequency response including Bode plots to illustrate gain in decibels and angular phase shift.
    Throughout the course, the use of circuit analysis software such as PSpice will be introduced. By the end of the course, students will be able to apply DC and AC circuit analysis as well as transient and frequency response analysis to complex circuits.

Drop Policy

Students may drop or swap (adding and dropping a class concurrently) classes through self-service in MyMav from the beginning of the registration period through the late registration period. After the late registration period, students must see their academic advisor to drop a class or withdraw. Undeclared students must see an advisor in the University Advising Center. Drops can continue through a point two-thirds of the way through the term or session. It is the student's responsibility to officially withdraw if they do not plan to attend after registering. Students will not be automatically dropped for non-attendance. Repayment of certain types of financial aid administered through the University may be required as the result of dropping classes or withdrawing. For more information, contact the Office of Financial Aid and Scholarships (http://wweb.uta.edu/ses/fao).

Americans with Disabilities Act

The University of Texas at Arlington is on record as being committed to both the spirit and letter of all federal equal opportunity legislation, including the Americans with Disabilities Act (ADA). All instructors at UT Arlington are required by law to provide "reasonable accommodations" to students with disabilities, so as not to discriminate on the basis of that disability. Any student requiring an accommodation for this course must provide the instructor with official documentation in the form of a letter certified by the staff in the Office for Students with Disabilities, University Hall 102. Only those students who have officially documented a need for an accommodation will have their request honored. Information regarding diagnostic criteria and policies for obtaining disability-based academic accommodations can be found at www.uta.edu/disability or by calling the Office for Students with Disabilities at (817) 272-3364.

Academic Integrity

At UT Arlington, academic dishonesty is completely unacceptable and will not be tolerated in any form, including (but not limited to) “cheating, plagiarism, collusion, the submission for credit of any work or materials that are attributable in whole or in part to another person, taking an examination for another person, any act designed to give unfair advantage to a student or the attempt to commit such acts” (UT System Regents’ Rule 50101, §2.2). Suspected violations of academic integrity standards will be referred to the Office of Student Conduct. Violators will be disciplined in accordance with University policy, which may result in the student’s suspension or expulsion from the University.

Student Support Services

UT Arlington provides a variety of resources and programs designed to help students develop academic skills, deal with personal situations, and better understand concepts and information related to their courses. Resources include tutoring, major-based learning centers, developmental education, advising and mentoring, personal counseling, and federally funded programs. For individualized referrals, students may contact the Maverick Resource Hotline by calling 817-272-6107, sending a message to resources@uta.edu, or visiting www.uta.edu/resources.

Electronic Communication

UT Arlington has adopted MavMail as its official means to communicate with students about important deadlines and events, as well as to transact university-related business regarding financial aid, tuition, grades, graduation, etc. All students are assigned a MavMail account and are responsible for checking the inbox regularly. There is no additional charge to students for using this account, which remains active even after graduation. Information about activating and using MavMail is available at www.uta.edu/oit/cs/email/mavmail.php.

Student Feedback Survey

At the end of each term, students enrolled in classes categorized as lecture, seminar, or laboratory will be asked to complete an online Student Feedback Survey (SFS) about the course and how it was taught. Instructions on how to access the SFS system will be sent directly to students through MavMail approximately 10 days before the end of the term. UT Arlington's effort to solicit, gather, tabulate, and publish student feedback data is required by state law; student participation in the SFS program is voluntary.

Final Review Week

A period of five class days prior to the first day of final examinations in the long sessions shall be designated as Final Review Week. The purpose of this week is to allow students sufficient time to prepare for final examinations. During this week, there shall be no scheduled activities such as required field trips or performances; and no instructor shall assign any themes, research problems or exercises of similar scope that have a completion date during or following this week unless specified in the class syllabus. During Final Review Week, an instructor shall not give any examinations constituting 10% or more of the final grade, except makeup tests and laboratory examinations. In addition, no instructor shall give any portion of the final examination during Final Review Week. During this week, classes are held as scheduled. In addition, instructors are not required to limit content to topics that have been previously covered; they may introduce new concepts as appropriate.
