AC CIRCUITS


COURSE DESCRIPTION

AC Circuits (ELE-212) is intended for students who plan to pursue an academic path in electronics. It continues and normally follows the course DC Circuits (ELE-211) and provides an introduction to alternating current, inductance, capacitance, inductive and capacitive reactance, fundamental ac circuitry, and single-phase transformer.

Knowledge of basic dc circuits (or a course equivalent to ELE-211, DC Circuits) and an understanding of basic trigonometric functions (or proficiency in a course equivalent to at least MAT-129, Precalculus for Technology) is needed to succeed in this course.

COURSE OBJECTIVES

After completing this course, you should be able to: 

  1. Identify a sine wave, square wave, and triangle wave.
  2. Calculate the period and peak voltage of a sine wave from a scope trace or graph.
  3. Use Ohm's law and Kirchhoff voltage and current laws to solve circuits containing resistors, capacitors, and inductors.
  4. Describe the behavior of both a capacitor and an inductor in an ac circuit.
  5. Calculate the currents, voltages, and phase angles in circuits containing resistors, capacitors, and inductors.
  6. Calculate the resonant frequency of an RLC circuit.
  7. Calculate the impedance at any frequency of an RLC circuit.
  8. Identify and calculate the three types of powers within an alternating current system: resistive (watts), reactive (VAR), and apparent (VA).


COURSE MATERIALS

You will need the following materials to do the work of the course. The required textbook is available from the College's textbook supplier, MBS Direct.

Required Textbook

  • Electronics Technology Fundamentals, Conventional Flow Version, 3d ed., by Robert T. Paynter and B. J. Toby Boydell (Upper Saddle River, NJ: Pearson Prentice-Hall, 2009).

COURSE STRUCTURE

AC Circuits is a three-credit online course, consisting of seven (7) modules. Modules include learning objectives, study materials (readings and exercises from the course textbook and self-check quizzes from the textbook's companion Web site), a written assignment, and a module-ending test. Modules 3–7 also include circuit simulation problems that you complete as a group activity. Module titles are listed below.

ASSESSMENT METHODS

For your formal work in the course, you are required to complete seven (7) written assignments, participate in five (5) group activities involving circuit simulation problems, and take seven (7) online module tests. You are also required to take a proctored midterm examination. See below for more details.

Consult the course Calendar for assignment due dates.

Written Assignments

You are required to complete seven (7) written assignments that consist of short-answer, essay-type questions and end-of-chapter problems selected from the textbook.

Online Participation

In addition to an ungraded Introductions Forum in Module 1, AC Circuits requires you to participate in five (5) group activities involving circuit simulation problems. Click link for the activities' ground rules.

Communication and collaboration among fellow students and with the mentor is a critical component of online learning. The circuit simulation problems provide an opportunity for you to apply textbook concepts and computational skills within an interactive team setting. In so doing, you can benefit from the help of your classmates and share your understanding of electrical circuits and chapter concepts.

You will be evaluated both on your group participation (i.e., how well you fulfill your team responsibilities of posting solutions, commenting on the work of others, and participating in team decisions) and on the quality of your work (i.e., the correctness and thoroughness of the final team reports).

Due dates for posting responses to the simulation problems are given in the course Calendar.

See Modules 3–7 for specific directions for completing the group activities and circuit simulation problems.

Module Tests

At the conclusion of each module, following the written assignment, is an online module test. The tests consist of  twenty (20) multiple-choice questions and are up to 45 minutes long.

Consult the course Calendar for test deadlines.

Midterm Examination

You are required to take a proctored midterm examination. The exam requires that you use the College's Online Proctor Service (OPS). Please refer to the "Examinations and Proctors" section of the Online Student Handbook (see General Information area of the course Web site) for further information about scheduling and taking online exams and for all exam policies and procedures. You are strongly advised to schedule your exam within the first week of the semester. Consult the course Calendar for the scheduling of this examination.

The proctored midterm exam covers all material assigned in Modules 1, 2, 3, and 4. It is two hours long and consists of 25 multiple-choice questions like those on the module tests.

The exam is open book, but not open notes. In this regard you are permitted to use only a scientific (nongraphing) calculator and the authorized textbook. You are not allowed to consult a solutions manual, notes of any kind (including graded or ungraded activities), or any other reference sources or sources of information. The use of blank scratch paper for doing math calculations is permitted during online test administrations.

Statement about Cheating

You are on your honor not to cheat during the exam. Cheating means:

If there is evidence that you have cheated or plagiarized in your exam, the exam will be declared invalid, and you will fail the course.

GRADING AND EVALUATION

Your grade in the course will be determined as follows:

All activities will receive a numerical grade of 0–100. You will receive a score of 0 for any work not submitted. Your final grade in the course will be a letter grade. Letter grade equivalents for numerical grades are as follows:


A

=

93–100

C+

=

78–79

A–

To receive credit for the course, you must earn a letter grade of C or better (for an area of study course) or D or better (for a nonarea of study course), based on the weighted average of all assigned course work (e.g., exams, assignments, discussion postings, etc.).

STRATEGIES FOR SUCCESS

First Steps to Success

To succeed in this course, take the following first steps:

Study Tips

Consider the following study tips for success:

ACADEMIC INTEGRITY

Students at Thomas Edison State College are expected to exhibit the highest level of academic citizenship. In particular, students are expected to read and follow all policies, procedures, and program information guidelines contained in publications; pursue their learning goals with honesty and integrity; demonstrate that they are progressing satisfactorily and in a timely fashion by meeting course deadlines and following outlined procedures; observe a code of mutual respect in dealing with mentors, staff, and other students; behave in a manner consistent with the standards and codes of the profession in which they are practicing; keep official records updated regarding changes in name, address, telephone number, or e-mail address; and meet financial obligations in a timely manner. Students not practicing good academic citizenship may be subject to disciplinary action including suspension, dismissal, or financial holds on records.

 

Academic Dishonesty

Thomas Edison State College expects all of its students to approach their education with academic integrity—the pursuit of scholarly activity free from fraud and deception. All mentors and administrative staff members at the College insist on strict standards of academic honesty in all courses. Academic dishonesty undermines this objective. Academic dishonesty can take the following forms:

Please refer to the Academic Code of Conduct Policy in the College Catalog and online at www.tesc.edu.

 

 

Plagiarism

Using someone else’s work as your own is plagiarism. Thomas Edison State College takes a strong stance against plagiarism, and students found to be plagiarizing will be severely penalized. If you copy phrases, sentences, paragraphs, or whole documents word-for-word—or if you paraphrase by changing a word here and there—without identifying the author, or without identifying it as a direct quote, then you are plagiarizing. Please keep in mind that this type of identification applies to Internet sources as well as to print-based sources. Copying and pasting from the Internet, without using quotation marks and without acknowledging sources, constitutes plagiarism. (For information about how to cite Internet sources, see Online Student Handbook > Academic Standards > “Citing Sources.”)

Accidentally copying the words and ideas of another writer does not excuse the charge of plagiarism. It is easy to jot down notes and ideas from many sources and then write your own paper without knowing which words are your own and which are someone else’s. It is more difficult to keep track of each and every source. However, the conscientious writer who wishes to avoid plagiarizing never fails to keep careful track of sources.

Always be aware that if you write without acknowledging the sources of your ideas, you run the risk of being charged with plagiarism.

Clearly, plagiarism, no matter the degree of intent to deceive, defeats the purpose of education. If you plagiarize deliberately, you are not educating yourself, and you are wasting your time on courses meant to improve your skills. If you plagiarize through carelessness, you are deceiving yourself.

Disciplinary Process

First-time incidents of academic dishonesty concerning plagiarism may reflect ignorance of appropriate citation requirements. Mentors will make a good faith effort to address all first-time offenses that occur in courses. In these cases, the mentor may impose sanctions that serve as a learning exercise for the offender. These may include the completion of tutorials, assignment rewrites, or any other reasonable learning tool including a lower grade when appropriate. The mentor will notify the student by e-mail. Decisions about the sanctions applied for subsequent plagiarism offenses or other violations will be made by the appropriate dean’s office, with the advice of the mentor or staff person who reported the violation. The student will be notified via certified mail of the decision. Options for sanctions include:
