Hi, My name is John. I hope you enjoy this little course. So far I have 14 lessons here, and a Basic Electronic Components description page. The first four videos are here for Lesson 3, 4, 5 and 6, more to follow.

Any comments about what you like or don’t like that would help me improve this site would be welcome. Thanks, John

1. Lessons 3 thru 6 now have videos.
Thanks, John

Posted a new video for lesson 4, Ohms Law part one. It goes over the calculations involved in a series resistor circuit. The calculations are explained step by step so a fourth grader could easily understand.

Then, after the calculations are complete, a meter is hooked up to show what the actual readings were.

Sorry for the delay,

Thanks,

John

1. That is very kind of you.

Now that they have my meds right, things are rapidly improving.

Thank you very much.

Due to having major surgery, I will not be able to add any more videos until probably mid to late September, God willing. Thank you.

In Basic Electricity, you displayed a model of an atom to display the setup of a basic atom of Hydrogen. However, the atom is described as (and displayed in picture) an atom of Helium, with 2 electrons, 2 protons, and 2 neutrons. The Hydrogen atom has 1 proton, 1 electron, and no neutrons, only isotopes have it. Can you clarify

1. EFF John says:

Asterwind, THANK YOU!!

You are of course, absolutely right! I had an image of a Hydrogen atom at first, but it wasn’t one I felt good about using. The images I use here all all either from Wikipedia, with a Creative Commons license, or created by me. So when I couldn’t find a Hydrogen atom on Wiki, I changed the image along with the description of how many protons, neutrons, and electrons, but forgot to change the name from Hydrogen to Helium.

I must apologize to my readers for that and credit Asterwind for catching my mistake. Good job Asterwind!

The rest of the lessons for THIS Basic Beginners course are now all online. The FUN STUFF will be experiments shown on videos, and I am just starting them. They will start showing up by July 31.

After that I plan on starting more lessons taking things to the next level. Thanks for looking, John
