Thanks a lot for the link! That thread seems a bit more geared towards design and high level projects.

To clarify, I've worked on a enough projects (hobby and professionally) to be able to get the job done (calculating resistance when needed etc), but want to gain a lower level understandings of electricity itself.

E.g. alternating current/negative voltages still seems really odd to me, which tells me I'm lacking fundamental knowledge. Hopefully this clarifies what I'm asking for, and thanks again for the link!

I think these 2 favorites of mine will help you:

- Tony Kuphaldt's books: http://www.allaboutcircuits.com/textbook/ and related forum http://forum.allaboutcircuits.com/

- "Practical Electronics for Inventors" by Paul Scherz

Both books start at explain-like-I'm-5 level and build up the narrative from there. The forum too is a great resource; lots of questions and good answers on fundamentals just like yours.

I will check these out! Thanks a lot I really appreciate it.

Some of the articles on Wikipedia are pretty good sources of fundamental knowledge. For example, here's their article on alternating current:
