ROSE-HULMAN INSTITUTE OF TECHNOLOGY Sophomore Engineering Curriculum ES 203 Electrical Systems Section 06 Course Information Instructor: Bruce A. Black C-208 Moench Hall 877-8437 [e-mail] Text: B.A. Black, Notes for a First Course in Electrical Systems. Terre Haute, IN: RHIT, 1998. Description: Electrical circuits play a central role in modern technology. Circuits can be found in applications as mundane as house wiring and as esoteric as the cellular telephone. ES 203 Electrical Systems continues the engineering science themes begun in ES 201 Conservation and Accounting Principles, but focuses on the principles of electric circuit analysis. In electrical circuits, energy storage is primarily in the form of electrical or magnetic energy, and energy conversion is primarily from electrical energy to mechanical energy or heat. Solution techniques will draw on Kirchhoff's celebrated laws as an adjunct to the conservation and accounting methods. ES 203 Electrical Systems plays a dual role in the curriculum. It parallels the Mechanical Systems and Thermal &amp; Fluid Systems courses in providing a balanced introduction to engineering systems. It also serves as the introductory course in electric circuits for electrical, computer, optical, and mechanical engineering majors. Follow-on courses continue in several directions. Electrical and mechanical engineering students will go on to take ES 205 Engineering Systems, in which the unified conservation and accounting techniques will be combined with specialized techniques to solve multi-disciplinary system problems. Students majoring in electrical or computer engineering will also take ECE 200 Circuits and Systems, where they will continue the formal study of electric circuits. Students majoring in mechanical engineering will continue their study of circuits in ECE 207 Elements of Electrical Engineering II. Engaging the Material: Mastering any new subject requires a continuous effort to make sense of new ideas and concepts and to relate them to what you already know. Learning to identify, formulate, and solve technical problems requires diligent practice in applying a logical problem-solving methodology. Learning to solve real-life engineering problems also requires a willingness to deal with ambiguity and uncertainty. You will achieve none of the objectives of this course by passively sitting in the classroom and waiting to be entertained by the instructor. Throughout this course it will by your responsibility to make learning an active process. Several suggestions of ways in which you can actively engage the course material are: Winter 2002-03 B.A. Black BAB 5/18/2009 5/18/2009 3860aa643c1a1d079c8868b2f3b245fbe95c8ca1.doc Page 1 of 3 ES 203 Electrical Systems Winter 2002-03 Come to class ready to participate and learn. Take notes in class. You cannot possibly write down everything your instructor and classmates say, so taking notes will encourage you to actively listen to identify what is important. Edit your notes shortly after class to fill in gaps and formulate questions. Ask questions! Do not hesitate to seek out your instructor for help. You will never &quot;reveal your ignorance&quot; by asking questions, but you sure can reveal ignorance on the exams if you don't ask questions. Read the text. Take notes on what you read. Verify derivations. Work the Maple examples. Try working the textbook examples without looking at the solutions. Ask questions when you don't understand something. Do all the homework. You cannot learn to play the violin by attending concerts. You cannot learn to solve engineering problems by watching your instructor solve them. Search out the underlying principle. Identify the central concept. Avoid the &quot;what's the formula for that&quot; approach to problem solving. Participate. Explaining your solution method to a classmate can be an excellent way of clarifying your own thinking about a problem. Ask questions. Examinations: Dates: Examination I: Thursday, January 9. Examination II: Thursday, February 6. Note: There will normally be no make-up exams. Examinations of one sort or another will make up 75% of your grade and warrant careful preparation. Examination questions will be based on the lecture material, the textbook, the homework, and the laboratory work. The two term exams will be conducted in class, and will each be of fifty minutes duration. Examinations will be closed-book and closed-notes. You will not be permitted a &quot;formula sheet.&quot; Use of Maple on your laptop will be permitted, as will the use of a calculator. Your laptop computers may not be used during examinations for access to other applications, files, or prepared worksheets, or for communication with other individuals. An examination that is missed for an excused reason will be waived. Excused absence from an examination normally requires advance approval or formal documentation of an emergency. An examination that is missed for an unexcused reason will be given a grade of zero. Grading: Grades will be based on examinations, homework, laboratory work, and class participation. The relative weights are shown below: BAB 5/18/2009 5/18/2009 3860aa643c1a1d079c8868b2f3b245fbe95c8ca1.doc Page 2 of 3 ES 203 Electrical Systems Winter 2002-03 Exam I: 20% Exam II: 20% Final Exam: 35% Homework: 15% Lab: 10% Note: Independent of point totals, <a href="/keyword/satisfactory-completion/" >satisfactory completion</a> of the lab is required in order to receive a passing grade in the course. Note: A 5% adjustment may be made at the instructor's discretion to take into account attendance, class participation, enthusiasm, overall effort, etc. This course is not graded on a curve. Everyone in the class has an equal opportunity to earn an A. At the end of the quarter grades will be assigned based on averages as follows: 90 and up...A 87 to 89......B+ 80 to 86......B 77 to 79......C+ 70 to 76......C 67 to 69......D+ 60 to 66......D below 60....F Attendance: Regardless of whether formal attendance is taken, attendance at each class is expected. A portion of the 5% discretionary points may be related to attendance. Experience has shown that regular attendance improves learning, and consequently improves test and homework performance. As a rule of thumb you should consider yourself seriously behind if you miss more than three classes in a three credit-hour course. It is an old joke that education is one of the few products for which purchasers pay a substantial sum of money and then often try to avoid consuming. Always bear in mind that each class missed costs you money, since you chose not to receive the services you purchased. Attendance in the laboratory is mandatory. Computers &amp; Calculators: Your laptop computer is a powerful tool that will significantly enhance your ability to solve circuit problems. We will make extensive use of Maple, and apply the techniques for solving linear systems of algebraic and differential equations that you learned in MA 221. Computers in the classroom can greatly facilitate the learning process, but they can pose a significant distraction if improperly used. Please do not use your computers during class to do homework, play games, read your mail, surf the web, or run software packages unrelated to the classroom activity. Failure to cooperate in this matter will certainly irritate your instructor, and can adversely influence your course grade!
