The convention in the USA is that the narrow prong is "hot" and the wide
prong is "common".  If you look at a wall socket, you will also see that 
the screw to attach the "hot" wire is brass- or brass-colored, and the
screw to attach the "common" wire is silver-colored.

You can also identify the "hot" wire in an outlet by using a Neon Lamp
type tester (the kind of tester which has a small neon lamp in a housing
and two test wires).  Hold one lead of the tester in your fingers and
touch the other lead to one hole of the socket.  If you are on the hot
wire, you will see a faint glow in the neon lamp (you may have to look
carefully).  You will see no glow on the common or ground.  Don't touch
anything else when you do this.  Don't do this with any other kind of
tester.  If you're not sure what kind of tester you have, don't do it at all.
