Course Description

Perhaps nothing is more representative of modern technological culture than electronic devices. But how do these often mysterious "black boxes" really work? This course presents an overview of the fundamentals of electric/electronic circuit analysis, starting with an overview of electrical theory and moving to simple circuit components like power supplies, resistors, capacitors, and inductors.

The course also provides an introduction to the actual circuit design, construction, test, and measurement, giving the hobbyist a jumping-off point for further pursuit of the subject. In addition, the course highlights some key concepts of semiconductors and semiconductor devices (like transistors). Finally, the lessons conclude with a look at some applications of the principles discussed throughout the course. The lessons are designed to serve students with a variety of backgrounds, and they require only a minimal level of mathematical aptitude (some algebra is helpful but not necessary to understand the main ideas of the course).

Each lesson provides a sufficient background to help novices understand the principles that underlie the operation of electric and electronic circuits. The course can serve as a review of the basic concepts of circuit theory or as a starting point for a more in-depth study of particular areas of interest, such as semiconductor devices, complex electronic networks, circuit design, and hobbyist electronics.
