Background
This is the second in a sequence of two electrical circuits courses. Success in this course requires a good working knowledge of algebra and trigonometry, along with a thorough understanding of the concepts presented in ET151 Circuits 1. Simply stated, this course is an AC version of Circuits 1. Combination RLC circuits are examined in great depth. Topics include impedance, frequency response, and resonance. Threephase power, transformers, and Fourier analysis of complex waveforms are introduced. If you do not already have one, purchase of a scientific calculator that will perform simultaneous equation solutions with complex coefficients is strongly advised. A minimum capability of 5 unknowns is desired. Examples include the TI86 and TI89. Also, it will be helpful to bring a set of colored pencils or pens to lecture (3 or 4 colors) because we create numerous simultaneous waveform plots. For lab, you'll need the standard array of goodies as used throughout this program (breadboard, DMM, small handtools, hookup leads, etc.) Unless otherwise specified, all lab exercises require a technical report due no later than one week after the exercise. Late penalty is one letter grade for the first half week, two letter grades for the second half week. Reports are not accepted beyond two weeks and receive a grade of 0. Remember, plagiarism is grounds for failure.

Weekbyweek progress and assignments
The problem numbers are for the 12th edition of the text. If you
have another edition of the text, please note that there
are some changes in the problem numbers. The laboratory manual may
be downloaded as a doc or pdf file at the bottom of this page.
1 
We begin with RC and RL transients. We then transition to AC concepts of time varying quantities: sinusoidal functions and waveforms, and calculation of average and RMS value.

2 
We finish chapter 13 and launch into chapter 14 with an examination of reactance and impedance. Read the notes on Fourier Analysis and Overtones.

3 
This week we introduce AC power and complex numbers. Complex numbers are extremely important you can't do the remaining material without them, so make sure that you master the concepts.

4 
We now begin elementary AC network analysis in chapter 15. The first topic is series networks.

5 
This week we look at parallel networks and introduce seriesparallel networks.

6 
We conclude with seriesparallel networks and have a test.

7 
Our next major topic is network theorems and analysis. This will be spread over a few weeks. This week we start with chapter 17 on methods of analysis (source conversions, dependent sources, mesh, nodal, etc.)

8 
We finish off methods of analysis and begin network theorems (Superposition, Thevenin, Norton).

9 
This week we conclude network theorems (Maximum Power Transfer, Substitution, etc). By midweek we'll begin AC power.

10 
We finish AC power this week and have a test. Then we begin another major topic: frequency response and resonance. We will be working through chapter 20 and 21 concurrently. Only a portion of chapter 21 will be examined, primarily as applications. The first item of interest is series resonance.

11 
This week we finish series resonance and start parallel resonance.

12 
When we have completed resonance, we begin with chapter 23, Polyphase Power.

13 
We finish off polyphase power and begin chapter 25, Transformers (end of the week).


We wrap up transformers and have our last inclass test (time permitting).
