CATALOG DESCRIPTION ES291 Electrical Circuits I CRN # 15158/ 10456 C3, P-2, CR-4 This course presents a calculus based introduction to linear circuit analysis for Engineering Science majors. This course heavily focuses on Electrical quantities, Applied laws & principles, and Electrical system modeling using DC & AC circuits. Items like Resistive circuits, Voltage & current divider circuits, Nodal & Mesh Analysis techniques, Thevenin, Norton, superposition, and source transformation, as well as Delta- Wye equivalent circuits and phasor analysis are also covered. Balanced three-phase and transformer circuits are also presented. Laboratory exposure & exercises are provided. Some computer based simulation tools are also introduced for comparative analysis. Corequisites: MA253 Analytical Geometry and Calculus 3 PH26 Engineering Physics 2 II. MATERIALS Text: Electrical Circuits y James Nilsson (9th edition) Addison Wesley Publishing company III.

Oscilloscope Orientation Disclaimer: The instructor reserves the right to alter any element of this syllabus including course content and policies that govern how the classroom operates. Academic Integrity: Academic honesty and integrity is expected in all work done for this class. Submitting the same work in more than one course without the permission of the involved instructors, copying the work of other students, using published work (Internet material is considered published work) without proper citation or otherwise attempting to receive academic credit for work that is not your own are all serious offenses which will result in a failing grade for the assignment in question and a potential failure in the course or even dismissal from the College. Classroom & Campus Civility: Mohawk Valley Community College is committed to civility in and out of the classroom. Everyone has the right to an environment that is conducive to learning. With that commitment in mind, conduct in the classroom is governed by the Student Code of Conduct which may be found in the Student Handbook and online. MVCC chooses respect for all individuals and classroom disruptions will not be tolerated SUSTAINABILITY STATEMENT Mohawk Valley Community College is committed to the development and implementation of a comprehensive sustainability plan. To that end, we are beginning by asking students, faculty, and staff to actively participate in energy conservation measures and proper recycling on the campus. The blue bins located in the classrooms and offices are for clean paper and paper products only. All plastics, metal, and glass containers should be placed in the proper recycling bins located in the hallways. (Please empty containers before recycling). Any materials that cannot be recycled should be placed in garbage cans. It is also important to turn off lights and computers when leaving a room. Together we can make an impact on conserving our resources. Remember to reduce, reuse, and recycle! DGV STATEMENT Two years ago, MVCC started a program titled “Diversity-Global view” (DGV), which gave each of our graduates a chance to participate in educational experiences designed to increase awareness of intercultural perspectives. Our goal in doing so was to enhance our students’ understanding of the realities faced by individuals as a result of their race, ethnicity, cultural background, gender, sexual orientation, socioeconomic status, academic abilities, and interests, age, religious beliefs, and physical ability. To that end, all graduates who matriculated into programs in the Falls 2008 or more recently, or who have changed their majors since 2008, are now required to complete the DGV components associated with the degree or certificate program in which they are enrolled. For more information, please visit: http://www.mvcc.edu/students/registration/dvgrequirements.cfm DISABILITY SERVICES I would appreciate hearing from anyone in the class who has any type of disability (e.g., physical, learning, psychiatric, vision, hearing, etc.) which may require some special accommodation. Please see me during my office hours so that we can discuss your needs. Before services can begin, you must also contact Lynn Igoe, Coordinator of Disability services, 7925413, or Tamara Mariotti, the Learning Disabilities and Assistive Technology Specialist, 7315702; Both are located in Room 153 of the Academic Building on Utica campus. (For classes on the Rome campus, the contact person is Michael Badolato, PC A30, 334-7718). They are the staff members who review documentation, determine eligibility for accommodations, and decide what those accommodations will be. MOHAWK VALLEY COMMUNITY COLLEGE Center for Mathematics, Engineering, Physical Science and Applied Technology- STEM POLICY SHEET 1. Attendance in this course is mandatory. Attendance will be taken in each class period. It is your responsibility to come to class and be on time. If you miss any class, again it is your responsibility to obtain lecture notes and handouts for any class you missed 2. Lab assignments must be finished on time 3. There will be 3 exams and a final exam 4. Exams will be conducted on the assigned dates. If you have an unusual circumstance to miss an exam, you must discuss this with the instructor prior to the exam. THERE WILL BE NO MAKE-UPS UNLESS APPROVED BY THE INSTRUCTOR PRIOR TO THE TEST TIME. IF A STUDENT MISSES AN EXAM, HE/ OR SHE WILL RECEIVE A ZERO FOR THAT TEST. 5. Academic Integrity: The college’s policy on academic integrity will be upheld. Do your own work on tests, labs, homework, and other evaluations. Engaging in dishonest and unethical behavior will result in disciplinary action by the college and the instructor. 6. FINAL GRADES Final grades are based upon the results of exams, lab work, quizzes, reports, homework and attendance as follows: Scheduled Exams 70% Home work/ Attendance 15% Lab Reports 10% Quiz 5% ALL WORK MUST BE COMPLETED IN TIME TO PASS THIS COURSE Late work will not be graded and will count as a zero
