MOHAWK VALLEY COMMUNITY COLLEGE UTICA, NEW YORK ENGINEERING TECHNOLOGIES AND THE TRADES DEPARTMENT COURSE OUTLINE I. CATALOG DESCRIPTION: ET120 SURVEY OF ELECTRICITY (Verizon) C-3, P-2, CR-4 This course provides a foundation for the learning of telecommunications applications circuits. Students analyze DC and AC passive circuits’ analysis using Ohm’s Law and Kirchoff’s Laws. RC and RL circuits are analyzed for impedance and phase angles. Troubleshooting, analysis by computer simulation using simulation software, and telecommunications applications are stressed throughout. This course is restricted to Verizon NextStep students. Prerequisites: II. MA119 Verizon Technical Algebra and Trig 2 IS101 Computer Applications & Concepts 1 or IS100 Introduction to Computer Applications & Concepts MATERIALS: Texts: The Science of Electronics: DC/AC : 1/e, Buchla and Floyd, Prentice Hall, 2005, ISBN: 0130875651 Experiments in Basic Circuits: Theory and Application 7/e, Buchla, Prentice Hall, 2003, ISBN: 0130986690 III. COURSE OBJECTIVES: The student will gain familiarity with the behavior of basic DC and AC electrical circuits including the interrelations of voltage, current, impedance and power. The student will demonstrate analytical skills and insights that will be applied to more advanced circuits encountered in later courses. The student will use a mathematical and problem solving approach for introductory circuit analysis, based on fundamental DC and AC circuit principles and math concepts. This will include the use of computer simulations. The student will gain facility at constructing and troubleshooting basic circuits in the laboratory with proper use of test equipment. The student will focus on appropriate communication skills, particularly technical reports through the laboratory. The student will work as part of a technical team, particularly in the laboratory. 1 IV.
