This book is fascinating not only because of it's content, but also because of the 1950's era cartoons that describe electricity to you. Well written and well drawn, this book is quite good. This particular edition does have a flaw, in that it doesn't include information on Transistors. Other than that, this book is quite excellent. Given the style of cartoons present, I can imagine a 1950's era announcer doing a dub of this book.
I found this particular copy in the Library, but if you can find it in a store or something it is pretty cool. I don't know what they updated in the later editions, but it still holds up I think, since the laws of electricity don't change at all from year to year. Certainly the stuff we can do with it has changed, but Ohm's Law, the Kirchoff Laws and others have not changed at all.
