I just thought I'd post this link http://users.pandora.be/educypedia/electronics/electricitycircuits.htm because I think its very good for anyone who wants to learn electronics, but also the hard stuff too. It includes links to some really good pages on things like RLC/RL/RC circuits, Norton's law, superposition's law, reactance and impedance, DC circuits, loop analysis, AC circuit theory, Kirchhoff's current law, and a whole stack of other good information.
