lamp cord, which color was for positive and which for negative... it

Uh, take a good look at some of your cords; note the subtle difference.
Take a look at the plugs for polarity. If you don't see the differences,
go to a good hardware store and ask the guy about it.

So tell us, which color of lamp cord is positive and which is negative?
