### ECE 2004 Electric Circuit Analysis (3C)

Introduction to the basic laws and techniques for the analysis of electric circuits. Calculation of the response of circuits with resistors, independent sources, controlled sources, and operational amplifiers. The transient analysis of basic circuits with R, L, and C components. An introduction to AC analysis and phasors.

What is the reason for this course?

Circuit analysis and design using discrete R, L, and C components are the most fundamental skills for electrical engineers. This course introduces these basic circuit elements and teaches modeling and analysis skills for the DC portion of these circuits, with a small introduction to AC phasors. This knowledge is critical for the studentsâ€™ future studies in all areas of electrical and computer engineering.

*Required for all EE and CPE majors*. Typically offered: Fall, Spring, Summer I. Program Area: Circuits and General.

*Prerequisites: C- or better in ENGE 1104 or ENGE 1204 or ENGE 1114 or ENGE 1216. Corequisites: MATH 2214; 2074*.

Why are these prerequisites or corequisites required?

This course requires ENGE 1104 and 1204, which provides the student with basic problem-solving skills, instruction in the use of the computer, MATLAB, and graphing methods, all of which are necessary in circuit analysis. MATH 2214 is a corequisite because it teaches the student how to solve linear, constant coefficient forced and un-forced differential equations. The corequisite of 2074 is required because it is the accompanying laboratory that develops experimental skills in the subject matter of the course. The students apply these skills in the second half of 2004. Note that ENGE 1204 is a bridge course for students who complete ENGE 114 and wish to transfer to ECE.

### Department Syllabus Information:

**Major Measurable Learning Objectives:**

- use analytical techniques and an appropriate combination of Ohm’s law, Kirchoff’s laws, equivalent circuits, node voltage analysis, and mesh current analysis to solve linear circuits containing resistors, capacitors, inductors, independent sources, dependent sources, and operational amplifiers by determining all DC voltages, currents, and powers;
- use differential equations to solve for time-varying voltages, currents, stored energy, and dissipated power in first-order (RL and RC) and second-order (RLC) circuits;
- represent simple sinusoidal voltage and current waveforms as phasors and use the phasors to analyze elementary alternating current circuits operating under steady state conditions;
- use Matlab or a comparable software package to do the calculations required in items 1-2 above;
- use PSpice to analyze the circuits described in items 1-3 above.
