Dr. Gregory J. Mazzaro Fall 2015 ELEC 201 – Electric Circuit Analysis I Lecture 0 Introduction to Electric Circuit Analysis THE CITADEL, THE MILITARY COLLEGE OF SOUTH CAROLINA 171 Moultrie Street, Charleston, SC 29409 Outline • Syllabus highlights • Course description, textbook, grading, etc. • Introduction to Dr. Mazzaro • Background, beliefs regarding education • Course objectives • Skills students will learn 2 Syllabus Discussion ELEC 201: Circuit elements; Kirchhoff’s and Ohm’s Law and their application through a variety of analysis techniques; operational amplifiers; transient responses of simple circuits. The circuit analysis program SPICE is introduced. NOTE: Students must earn at least a “C” in ELEC 201 before enrolling in any courses for which ELEC 201 is a prerequisite. • first “core” class for electrical engineering majors • applies earlier knowledge (physics, mathematics) to circuits • follow-on course: ELEC 202: Sinusoidal analysis and phasors; AC power; three-phase circuits; frequency response of simple circuits; use of SPICE for AC circuits. 3 Syllabus Discussion Schedule: Section 01, MWF 08:00-08:50, GRIMS 305 Section 03, MWF 09:00-09:50, GRIMS 305 Section 02, MWF 11:00-11:50, GRIMS 305 • Attendance is mandatory. 20% absence = “F” grade, miss a quiz/test = 0 score • Notify your instructor if you must miss class for any reason. You are responsible for learning the material that you missed. • Attend your assigned section. Exceptions will be allowed under extreme circumstances only. 4 Syllabus Discussion Textbook: R. C. Dorf & J. A. Svoboda, Introduction to Electric Circuits, 9th Ed., John Wiley & Sons, 2013. • same book for ELEC 201 as last year • If there are any concerns/issues regarding the book, discuss them with Dr. Mazzaro: -- typographical errors -- incorrect problem solutions -- not enough worked examples -- info that conflicts with lectures 5 Syllabus Discussion • personal, portable Circuits lab • used for HW assignments & labs 6 Syllabus Discussion Website: http://ece.citadel.edu/mazzaro (“ELEC 201” on left-hand menu) • lecture notes: can be printed ahead of each class • homework: assignments, solutions, frequently-asked questions • quizzes: solutions • tests/exams: review packets, solutions • important dates and announcements Students should check their course websites regularly. 7 Syllabus Discussion Grading: homework: written (7) homework: simulations homework: projects quizzes (2, announced) in-class exams (3) take-home exam final exam (comprehensive) 10% total 10% total 10% total 5%, 5% 10%, 10%, 10% 5% 25% Grade breakpoints: 90% A < 100% 80% B < 90% 70% C < 80% 60% D < 70% F < 60% • Homework is due at the start of class on the assigned due date. • Every exam is cumulative. 8 Dr. Mazzaro Instructor: Dr. Gregory J. Mazzaro, Grimsley Hall Room 312 phone: 843-953-0429, e-mail: gmazzaro@citadel.edu office hours: (posted on the course website) Experience Electronics Engineer, U.S. Army Research Laboratory, Adelphi, MD, 2009-2014 Education Ph.D., Electrical Engineering, North Carolina State University, Raleigh, NC, 2009 M.S., Electrical Engineering, State University of New York at Binghamton, Binghamton, NY, 2006 B.S., Electrical Engineering, Boston University, Boston, MA, 2004 9 Dr. Mazzaro Beliefs, regarding Engineering & Education (1) Engineering is fundamentally different from other fields. Students build a “toolbox” of analysis & design techniques in preparation for becoming employed. (2) Learning & teaching are best accomplished when students and professors establish a (professional) familiarity with each other. -- students know what their professor expects of them -- professors know the pace at which their students learn -- students convey their goals to their professor -- professors are easily accessible to students outside of class (3) Students deserve immediate feedback on their assignments (e.g. quizzes, homeworks, exams). 10 Dr. Mazzaro Classroom environment • each “lecture” should be a dialogue -- Questions, comments, and concerns are welcome. -- You are free to interrupt (politely). • my questions to you are intended… to be simple (i.e. not a trick) to gauge your understanding to foster discussion Grading • particular assignments, tests: tough (i.e. a very high standard) • overall course: depends on each student’s level of effort • no curves (on any graded work) 11 Supplemental Instruction Purpose: to provide students with a systematic and disciplined approach for processing material assigned by the professor Who: a student who has demonstrated proficiency in the subject and who has undergone a rigorous SI training program (Christopher) Tyler Bray major = electrical engineering cbray3@citadel.edu office hours: Tuesday 20:00 to 22:00 Thursday 20:00 to 22:00 GRIMS 305 If you want/need help, don’t hesitate.
