Learn About Electronics grows and grows

Learnabout-electronics was initially designed as a small website, part of a degree course in web technology at the University of Lincoln, UK. It developed further as a study into international on-line learning at Stanford University, California.

Now with around 250 pages and over 1000 illustrations and animations on a wide range of electronics topics, the website has grown into a major international educational site, with millions of independent learners, and students from colleges and universities all over the world finding the electronics information on learnabout-electronics among the best available.
Learnabout-electronics continues to develop with new topics and new modules being developed continually. The aim of the site remains constant however. To provide the best possible on-line learning experience, freely available to all. Learnabout electronics modules can be easily translated using Google Translate, making them available in over 50 languages.

From 2013 all new modules, beginning with the modules on Oscillators, are being developed in HTML5 and designed with new responsive pages to display better on mobile devices, so now it will be easier to learnabout electronics on the go!

Please use the Contacts page to let us know how the new style pages, now with space saving drop down menus and responsive layouts, work for you. Whether you view learnabout-electronics on mobile devices or on desktops your, experience of the site is important.

AC Theory

Our pages about AC components and circuits are designed to teach the basics of AC Theory in 11 easy to learn modules. Use them as a complete course, or study any individual topic, including capacitors, inductors, reactance, impedance, waveforms and phasors.

Every module is backed up with a paper version to download, print and keep. The online pages also use brand new interactive animations, adding to our popular transistor animations that are now among the most sought after diagrams of their type on the web. More pages being added regularly and more topics are being planned, so keep checking Learnabout Electronics...

Learn About Oscillators!

Sine wave, square wave, transistor, op amp and IC oscillators play a vital role in most electronic systems. How oscillators work and what they do. Radio frequency and audio frequency circuits, astables, monostables and pulse width modulation are all here in our popular learnabout modules

Learn about oscillators step by step, or choose any module and learn just what you need to know, including to how to design and build working circuits for yourself. How to test oscillators, plus links to relevant electronics industry oscillator data!

 

Electronics

Quality teaching materials for your electronics classes, and links to selected electronics sites worldwide for further information. Learn on line, or download printable .pdf versions of key information or whole learning modules to print and keep.

For Teachers

This site is designed to take your students one stage further in an interesting and informative way. The information will be suitable for students studying on a wide range of electronics courses and is used world wide, anywhere a practical understanding of electronic components is needed. It will provide useful support material for advanced students, and key information for students new to electronics.

For Students

Learning about electronics? Then you need to know about components; on our site you will find full and easy explanations of many common types. Check out our animated diagrams to make transistor operation clear. Find out the right way to test transistors in our Fault Identification Section and get help with those maths problems you need when starting out in electronics.

Step by Step

Check out AC Theory, Amplifiers and Oscillators, with our "Step by Step" learning modules, designed at Stanford University School of Education.
Each module starts with "What you need to know", followed up with informative text, clear illustrations and interactive animations to help you learn. At the end of each module a short quiz helps you check what you have learned. A paper version of every module is also free to download to print and keep. Nothing to pay! No need to Log in. Try it!
