Wow, how about a semester at MIT? "Electricity and Magnetism"
 

I don't know about you, but I find this stuff fascinating. The first is the intro to the "open courseware" (don't really need to watch.) The second is lecture 1 on Electricity and Magnetism.



Go to youtube and look under the info panel and "Series" for the list of the rest of the lectures (there's nearly 40, each about 50 minutes).
