One goal of this book is to provide practical information to better equip the reader to put circuit theory into practice. The picture on the cover of this book shows an example of a RLC circuit built on a breadboard. After the completion of this book you will understand how RLC circuits work and many of the applications they are used for, as well as obtain a foundation in electronics. While providing practical information, this eBook tries to avoid going into too many tangents that result in numerous pages being skipped over by the reader. Links are provided throughout the eBook where more background information is available when I felt the temptation to depart from the main point.

The circuits in this eBook are created with a user friendly circuit drawing and simulation tool called Multisim. Creating new circuits and simulating them to verify that your calculations are correct is a good way to hone your circuit analysis skills. By providing an explanation of how to verify calculations in Multisim, this eBook enables the reader to create more complicated problems, while having a method to check the results. This is vitally important with AC circuits because the complex algebra involved in solving them is very tedious and mistakes  are frequently made by students that are learning the problem solving techniques. The DC probes and Multimeters were used extensively in the DC Circuits eBook, but in this eBook AC probes and the MultiSim oscilloscope will also be used to make more complicated AC measurements.
