Sub-ordinate teacher:
Dr. Scott D. Johnson, Associate Professor

Course Description:

Principles of circuit analysis, including Kirchoff’s laws, node and mesh analysis, transient analysis of first and second order systems, DC and AC steady state, phasors, and Thevenin and Norton theorems.

Required Texts:

Electric Circuits, (7th Ed) Nilsson and Riedel, Prentice Hall


a) Differential Equations (MAT 246 or equivalent). This can actually be taken concurrently with EGR 203 – more accurately, Diff. Equations is a co-requisite.

b) Physics I – PHY 103

Course Objectives:

Upon successful completion of this course, a student will be able to:

1. Apply Kirchoff's voltage and current laws to linear AC and DC circuits

2. Apply the branch relationships for sources, resistors, inductors and capacitors, in both the time and frequency domain.

3. Reduce impedance-source networks to single impedance-source - Thevenin/Norton equivalents.

4. Use phasors in the analysis of AC circuits

5. Determine the natural and step responses of 1st and 2nd order circuits.

6. Analyze several fundamental operational amplifier circuits to determine their input-output relationships.

Course Guidelines:

This is an advanced course. As such, I will expect you to display an appropriate level of professionalism. I will assign reading from the text, and will expect and assume that you have read the assigned material before coming to class.

Testing/Grading policy

Your grade will be based upon four factors. The first of these, composing 20% of your grade, is graded homework. This will be in various forms – a series of problems assigned from the text, a special problem from outside material, or some sort of small project. The due date is a "hard" date – if you don't turn it in on the date due, you will loose 20 percent of the possible grade points for each day late. Please note that this graded homework is NOT the “suggested exercises” shown in the course schedule below – those are for you to do or not as you see fit (but obviously, it's to your advantage to do them). Assigned, graded homework will be posted under “weekly topics”, and I will make an announcement about it as it is posted. The second component of your grade (worth 40%) is determined by periodic tests. There will be four of these, given roughly every 3-4 weeks throughout the class session. The third part of your grade is the final exam, which will cover ALL the material we have covered in the class. The last 10 percent of your grade is class participation. You get these points by demonstrating your active participation thru contact with me (or Dr Johnson, see below), taking all the tests, doing all the assigned homework on time, etc.

I will use the Testing Center for our exams and the final. You will have ample time to complete these tests, as the testing center does not enforce a time limit. I will provide you with information on the Testing Center as it becomes necessary. Bear in mind that your final will have a limited time allotted. unlike the other exams, so be sure that you don’t get in the habit of assuming you have unlimited time to work on tests.

The last day to officially “withdraw” from the class without penalty is the 21st of April. I’ll be sure to give you opportunity to determine if you need to take advantage of that date. At this stage of your academic career, you should not need to. However, I understand that things happen, so as long as you drop the course through the registrar prior to the 22nd, you can receive a “W”.

Office Hours

Since this is an "on-line" class, my office hours are a bit more flexible. We can meet in the virtual classroom (see the"Tools" button on the left hand side of your Blackboard page) at the regularly scheduled times posted in my permanent announcement, or you can email me at jbailey@pgcc.eduand set up a time to meet with me. You also have the option of going to see Dr Johnson ( in his office,Chesapeake 310-C, but you will need to make arrangements with him as to time and day.

Academic Honesty

It should go without saying that I expect each of you to comport yourselves with honor and dignity. For those who find this difficult, there is a school policy on the matter. It is contained in the Student Handbook, which each of you should have. They are available in the Student Activity Center on the first floor of the Largo Student Center (next to the Rennie Forum). Naturally, I will adhere to that policy.

If you need some accommodation for a disability, see the folks in the Disability Support Services office (301-322-0838 or TDD 301-322- 0122). They will provide you with a form which you can then give to me, and I will make whatever accommodation necessary. But, YOU MUST SHOW ME THIS FORM. Otherwise, I cannot make any accommodation.

With that out of the way, let me tell you a bit about myself and my approach to this class.

I am a communications engineer and an applied mathematician. My doctorate is in Operations Research (think of it as the application of math to decision making), but the majority of what I have done in my professional life is related to mobile communications.

You are embarking on a journey that, when successful, results in your achievement of some professional goal you have chosen. This course is the beginning “hard core engineering” for EE’s and Computer Engineers. It is also an excellent course for other branches of the engineering profession, since most at some time get exposed to the topic. For example, civil engineers and structural engineers worry about

how materials react to forces applied on them. The classic way of measuring this response involves using electric/electronic devices. Understanding a bit about such circuits will be very useful.

My job is to help you learn this material. The operative phrase in that last sentence is HELP YOU LEARN. This is not something that happens without active involvement on your part! I cannot somehow force the material into your brain; you must make a positive effort to learn the material. I’m here to help you do that. My comments about professional behavior above apply here too. By now, you have been in college for a number of semesters, and you should understand that your success is up to you. My role is that of a facilitator.


            See the document after this or "Weekly Topics" for an approximate timeline for topics in this course.  Since this is on line, you have some freedom to do things at your pace, but I will not post material more than a week prior to our covering it.  You can go back to old material, but I'd rather you not go too far ahead.  The material in this course is mostly presented in a specific order for a reason, and if you skip ahead you may not have the tools yet to understand or gain the most from this new material.
