Pre-/ Co-requisites: Physics 117
Text: Fundamentals of Electric Circuits, by Alexander and Sadiku, McGraw-Hill, 2017, 6th ed.
NOTE: You may use older editions, since not a lot changes in the text. However If you decide to use an older edition of the text, it is YOUR RESPONSIBILITY to make sure you are aware of any differences between the edition you are using and the most recent edition.  

   

Course Overview and Objectives
The basic objective of this course is to introduce students to the fundamental theory and mathematics for the analysis of the flow of electrical energy through electrical circuits. Through the material presented in this course, students will learn:

  1. How eletrical and magnetic energy interact with matter, focusing on linear behavior
  2. The fundamental principles in electric circuit theory and be able to extend these principles into a method of thinking for problem solving in mathematics, science and engineering
  3. To analyze analog circuits that include energy storage elements in the time and frequency domains, both theoretically and experimentally
  4. How to predict the behavior of these basic electric circuits
  5. Ways in which electrical engineering shapes and benefits society
  6. To improve oral, graphical and written communication skills
  7. How to learn and to work effectively both individually and in groups
  8. To evaluate personal learning process and understanding of the concepts and skills from class

ABET Outcomes for EGR 220
For students' Books of Evidence, the following ABET outcomes can be achieved by every student taking EGR 220. Note that this is a shared responsibility between the course professor and each student. If you do not understand how or when these outcomes are being addressed through the course material, be sure to come to office hours (while there are still many weeks remaining in the semester). If populating your BoEs is left until the end of the semester, it could be too late to achieve all you planned.

  • Student Outcome (1a)
    • (1)a: The student formulates and solves a complex engineering problem that requires mathematical skill and principles from solid mechanics, fluid mechanics, circuit theory and/or thermodynamics..
  • Student Outcome (3c)
    • (3)c: The student presents engineering concepts utilizing a graphical representation.
  • Student Outcome (6): an ability to develop and conduct appropriate experimentation, analyze and interpret data, and use engineering judgment to draw conclusions
    • (6)a: The student designs an experiment and carries it out.
    • (6)b: The student demonstrates an ability to make quantitative measurements and assess sources of error.
    • (6)c: The student analyzes data and draws conclusions based on those data.
  • Student Outcome (7b)
    • (7)b: The student demonstrates resilience, adaptability, and iterative learning.

 
Note: In general, we will be skipping the PSpice sections of the book. The sections as listed below are intended to skip the PSpice reading. If they appear to be shifted in some chapters, please let me know.
