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.

This ties back to some of the stuff we discussed in your thread called "Transient Perfect Crossovers." Armed with this information, you can look at the issues we discussed and gain a complete understanding. It brings an appreciation of the Spice circuit modeling tool too.
