### ECE 2054 Applied Electrical Theory (3C)

For students in the Mechanical Engineering program or by permission of the ECE Department. Fundamentals of electric circuits: circuit laws and network theorems, operational amplifiers, energy storage elements, response of first and second order systems, AC steady state anlaysis. Construction, analysis, and characterization of circuits with student-owned Lab-in-a-Box system.

What is the reason for this course?

This couse is designed as an introductory course to the fundamental principles of electrical engineering for mechanical engineering students. It is necessary to grasp the material in this course in order to continue in the other ECE courses designed for non-electrical engineers such as ECE 3254 and ECE courses that are designed for students who are interested in inter- and multi-disciplineary topics that form the core of the Minor in Microelectronics. This course introduces the basic circuit elements and teaches modeling, electrical laboratory techniques, and analysis skills. The experimental skills developed during the laboratory portion of the course will be applied and built upon in ECE 3254.

Typically offered: Fall, Spring. Program Area: Circuits and General.

*Prerequisites: PHYS 2306; Co: MATH 2214*.

Why are these prerequisites or corequisites required?

This course rquires Physics 2306, which provides the student with the basic current and voltage concepts which are necessary in circuit analysis. The PHYS 2306 prerequisite will be strictly enforced as the knowledge developed in that course will be used extensively in this course. Mathematics 2214 is a corequisite because circuit analysis requires that the student know how to solve linear, constant coefficient forced and un-forced differential equations. Mathematics 2214 is a corequisite rather than a prerequisite because this differential equations material is not required until the middle of the semester.
