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!
