  • It makes no difference whether you are a beginner or someone simply looking into the possibility of doing some work in electronics technology ...

  • It makes no difference whether you are a student or practicing professional ...

There is something here for you.

Very few technologies require such high levels of both theory and hands-on skill as electronics. (Maybe brain surgery, but electronics is on that same list). Come on in and look around. If learning something or something more about electronics is on your do-list, you've arrived at the right place. 



Electronics is cool. I should know ... I spent a portion of my life working with military and civilian electronics; and then an even larger portion teaching and writing about it. And you know what? After fifty years, I've never grown tired of  it.  ~Dave Heiserman


Overview of Electronics


Activities are intended to get you directly involved in a learning program. There are a number of different types of activities--flash cards, Endless Examples & Exercises, research projects, and more.

Ohm's Law. Endless exercises for solving Ohm's Law. The real value is not simply knowing how to use the Ohm's Law equation, but rather the skills required for working problems using scientific notation.

Calculating DC Power Levels. Endless exercises for solving power equations for dc circuits. The real value is not simply knowing how to use the power equations, but rather the skills required for working problems using scientific notation.

Basic Electronic Circuit Analysis An extensive series of interactive circuit-analysis exercises, from finding the total resistance of a simple series circuit through a total analysis of complex RCL circuits.

Note: Some of these tutorials might require a PDF reader. If you do not have an the Adobe Acrobat Reader installed on your device, you can download a free copy here. Many also require the Google Play app for mobile devices.

Study Topics

Are you aware of every sub-discipline in the category of engineering technology? Perhaps not.


You might discover something very exciting that you didn't know existed!




I hope you understand that the purpose of Free-Ed-Net is NOT to sell you stuff. Zillions of other sites are fully dedicated to that purpose. I simply want to help you discover what can be so compelling and downright exciting about electronics. However, it is also fun, and even necessary, to do some hands-on electronics--and that means spending some money for instruments, components, and supplies. So you will see some ads for such things sprinkled here and there on the site.

Sitting here, 55 years into electronics, I can say there is no better resource reference and learning resource for this time than this book. (I wish I had written it.)
