Linear Circuit Analysis is a core course in electrical engineering that most undergraduate students need to take in the first year of their program. In fact, the course covers topics that are so fundamental that, most often, students from other engineering areas such as computer, industrial, power, or manufacturing engineering also need to take it as an introduction to electrical engineering.

This webbook is designed to be used by students to learn linear circuits while solving problems on the CircuitsU website; instructors can use the website to teach linear circuits without the need for other textbooks. This webbook and the problems generated by CircuitsU, cover most topics in the Linear Circuit Analysis course taught in undergraduate programs in the U.S. and is organized relatively similar to the existing textbooks on linear circuits.

The webbook is slightly different from other books or materials in linear circuits that you can find online. First, the webbook is written in a concise manner to make students spend a minimum amount of time learning the different topics on linear circuits and be able to spend more time practicing problems on their own. For this reason, just by browsing the pages of the webbook might not be sufficient to master all the topics on linear circuits (like a regular textbook is supposed to do) and students should first review the Examples of Solved Problems sections that appears at the end of most sections and then practice using the Practice Problems sections.

Second, the problems and examples that appear at the end of each section are generated randomly when the page is loaded, so students can look over and practice as many problems as they want. Due to the relatively large computational cost required to genearate random problems, you need to be logged in order to take advantage of the full set of examples and problems at the end of the sections.

Have fun!
