I have often had the same problem - all it takes sometimes is one person to think up just the right search terms and this list is great for that :) I looked at the article again and I do still think it is a good article, but it also has a number of embarrassing mistakes. It has many typographical errors and a few grammar errors. Worst of all, though, in discussing 3-phase power it says "the net energy delivered sums to zero" when I believe they meant to say "the net CURRENT delivered sums to zero".
