- Course Rationale and Goals
Course Rationale and Goals
Goals: To develop the fundamental tools of linear circuit analysis which will be useful to all engineers. To learn the "alphabet" of circuits, including wires, resistors, capacitors, inductors, voltage and current sources, and operational amplifiers. To prepare students for more advanced courses in circuit analysis.
Learning Objectives: At the end of this course, students will be able to:
- Identify linear systems and represent those systems in schematic form
- Apply Kirchhoff's current and voltage laws and Ohm's law to circuit problems
- Simplify circuits using series and parallel equivalents and using Thevenin and Norton equivalents
- Perform node and loop analyses and set these up in standard matrix format
- Identify and model first and second order electric systems involving capacitors and inductors
- Predict the transient behavior of first and second order circuits
- ASSIGNMENTS
ASSIGNMENTS
The homework assignments:
· The first page must be the title page. The title page must contain the name, surname and the number of the student. It should also contain the due date.
· Please also include a table of points for each problem.
· The solution must contain all the necessary steps.
· Remember that you must turn in the homework on the assigned days. Late submissions will not be accepted and graded.
Here is a sample title page. (You may download the .doc file and change the necessary information)
Important Note: You may discuss the homework problems with your friends for exchanging general ideas, but you may not copy from one another. You may also not give any parts of your homework to other students to look at. Any students violating these rules or committing any other acts of academic dishonesty WILL be turned over to the disciplinary committee for disciplinary action.
