Free Online Courses

Posts Tagged ‘electricity’

I am interested in learning how buildings like houses, offices, etc. are wired. I want to learn the practicalities of electricity, not the math-based circuitry crap I’ve been learning. Do I have to take a class at a trade school for this, or do many community colleges offer courses like this?
The closest class at a community college I could find is called ‘electrical inspection,’ but that is pretty vague.
Any recommendations?

Thanks.

Would like to find free or very low cost online courses on a variety of subjects like economics, electricity, various computer applications, history, etc. Whatever piques my curiousity at the time.

Ideally, the courses would be audio/video and have some interactivity like a short quiz after each section.

Also would be interested in courses offered on DVD or CD, but again, free or cheap.
Doesn’t have to be university accredited. This is strictly to satisfy my own curiousity about the world around me.
