Where can I find a course on electricity?

I searched for "electricity" in the search bar, which returned nothing.

Then I looked in "Science," and found "Electrical Engineering." I thought that was it, but it wasn't. It started off with atoms and electrons, and the positives and negatives, as if I should already know what they are and how they behave. I'm a total idiot when it comes to electricity, the only thing I can do is change a light bulb. I want to learn about how electricity works, from the ground (idiot level) up. Is this course available?

Sorry about this post. I couldn't find where to contact support by email or anything, there's only a forum avaible, so I had to come here.
