I love pretty much anything technical, whether it be programming, networking, hacking or electronics.

岩倉 澪:

You might want to check this out:

http://www.falstad.com/circuit/

Its not a real circuit simulator, but its close enough for educational purposes.
You can drag in various components like LEDs and power sources and it will help you visualize how the current is flowing
Playing around with this might give you a better idea of how the LED circuit is actually working.

There is a Java version of the sim that might run a little bit better then the in-browser one, link at the bottom....

I've been wanting to make my own version of this type of application, but haven't gotten around to it.
The Falsted simulator is unique from most simulators that I have seen in that its designed to be really easy to use intuitive.

Also, simulation is no substitute for playing around on a breadboard with some components :)

ooo, this looks like it will help a lot when we get to studying the hardware more. Thanks for the link! Do you know of any good online courses about circuitry?

https://electronics.stackexchange.com/ lets you ask your electronics questions. Standard SE Q&A rules apply: look if it's not a dupe yet, try and solve it yourself first and show your research/work if possible, if possible spend a paragraph describing what your goal is to avoid XY problems.

Besides that I've enjoyed Great Scott on youtube, He has a playlist where he explains basic components though not in a logical order.

No I'm not aware of any good introductory courses, Sorry :( I'm sure that there are i've just never used one...

I think EEVBlog is a good resource, I sometimes think of him as the Casey of electrical engineering. But his stuff isn't as structured though, and its mostly pretty advanced...

The best I can do is point you to the fundamentals:
1. Know ohms law: https://en.wikipedia.org/wiki/Ohm%27s_law
2. Voltage vs Power vs Energy: https://www.youtube.com/watch?v=YdbhnmA4M9g
3. Know Kirchhoff's: https://www.youtube.com/watch?v=WBfAEeEzDlg
4. DC Circuit analyses: https://www.youtube.com/watch?v=8f-2yXiYmRI

Feel free to ask me stuff :)
