The Electronics 101 series has done more to teach me about basic electrical fundamentals than any other text or training i have used. I have tried technical books, ARRL books etc. and FINALLY a simple course that managed to get right in this guys thick head. Cant express enough how the simple terms and examples, fine graphs and diagrams, and exercises helped me!! This should be the basic introductory to electronics that everyone uses--@52 years of age i finally think i understand. 73 Kelly

I really wanna appreciate and congratulate this electronics theory website because of their explainations which are through out clear as compared to other sites which are even tough to beginners. I found this website using my phone(NOKIA 2760) which i use opera mini software as a browser to browse the website's info. Am a Telecommunications and electronics engineering student in the first level of the course pursuing for a certificate. So when things are tough at college, thank God this website is here for reference. Way to go

This site is just awesome. I thought that from a very young age, I would be forever electronics retarded. But not only the work on the website must you be commended, but the fact that you are a natural teacher. If it wasn't for your excellent communication skills in how you exemplify things to how you've outlined the information...I would have absolutely NO hope in ever understanding electronics. Thank you very much for all your effort. I now understand and enjoy electronics. Sincerely, George

Sir,
I have been a Coast Guard Electronics Tech for 6 years and am currently using your course to brush up on electronics theory in preparation for a service wide advancement test. I am confident that with the aid of your exceptional training guide I will be head and shoulders above the rest of the sailors I am competing against. I would like to extend my gratitude for making this course available online.
Very Respectfully,
Louis

   Our Response:
   Louis, we appreciate all that you do.
   Let us know how well you do on the test!
His Reply:
I took the test and scored 100%. Those results speak for themselves, as does your course. Thank you again.

Hello,
I was looking for online courses for electronics and found your site.
WOW!
Are you telling me this is free?

I'm learning more about electronics from your online course than I have in all my years of self study. Your course brings everything together in one quick and understandable flow of knowledge. I'm anxious to continue learning about vacuum tubes...... Thanks, David

I am a technical writer (external contractor) assgined to develop some training materials for an FAA repair station in Miami... I have been assigned to produce some high level electronics training materials. I would like to use some of the material I found at http://www.electronicstheory.com. I will surely give you credit in the references, hopefully increasing traffic to your site. May I implement some of the material in my course manuals. I spent 8 years in the US Navy as an Avionics Technician and know the material but this would be of great help to me. Best regards, Thomas Myers, M.S.

I want to convey a grateful and heartfelt thanks for your course. I've been struggling with electronics for years, and since reading your comprehensive course, I now know more about how electronic components work individually, and together as a circuit. KUDOS! Mark B. Pittsburgh

I am from South Africa and I would like to commend you on a brilliant course. I am teaching electronics at a technical college and have found that the material is just what the doctor ordered. May I have permission to use all the course material for the benefit of my students. Once again a brilliant job. Keep it up - Thanx - M.Gobind, UFET College

Hi, Was browsing the web while on vacation and stumbled across your site. Looks like it will save me a lot of graphics work. I just prepareing to do something similar to help get those junior engineers trained. Now I will just have them browse your course. I have been in broadcasting since 78 and I'm sure you know the drill. One or two "real engineers" and the rest are fresh out of technical school and can't even spell klystron. I just wanted to let you know that I liked what I saw. Good Work. Larry ........ Assistant Chief Engineer ((TV Station Call Sign Listed Here))

Dear Mr Dall, I am a vocational instructor for ..... ...... I use your wrtten information to teach students about electricity and electronic applications. In the spirit of the law, I would like your approval for continue use of your text for my students. Thank You Abel

I was so happy to find your web site. It is really helping me. My boss recently bought another small company which manufacturers Transformers. I am the Marketing Mananger. Two years ago he bought a Nucear Engineering Firm which designs custom shielding for Radioactive Waste. I just got that down, and whammo... he buys another company. Now I am scambling to learn about Transformers. I am sure this site has taken you a very long time, and I really appreciate someone of your dedication. Thanks -Lynn

Just writing a small note to say thanks for your Fundamentals of Electricity web site. I am a mechanical engineer doing an electrical / mechatronics course and was finding it hard to make the crossover from mech. to electrical. The electrical circuits with mechanical equivalents really help to simplify it for me. Once again Many thanks Robert

Wow! I really like your online electronics tutorial... I just spent about 4 hrs refreshing myself with your site. Congratulations on a grea site... and see you around. BJ Computer Tech and old Video Game repairman :)

I teach at ..........Technical College. I am constantly looking for help for my basic electricity classes. Yours is very good. It would be wrong to direct a student to it and not commend you, Thanks, Bob

As a relative newcomer to the industry, I have suddenly found myself in the position of assistant chief engineer. Our transmitter is a Varian. Anyway, I have looked up and down for info such as you provide so that I don't appear too stupid to the bosses. Was sure glad to come across your page. Thank you. Best regards, Fred
