Blue and brown wires inside my PC's PSU....which is hot? Also, where can I learn some basic electric skills and knowledge so I'm not always deathly afraid.

I'm working on a project where I've ripped apart an old PSU from a PC. I'm trying to rig things so I can plug the PSU into the wall with the standard 3 prong cable, and run an extension cord off the inside of the unit.
Basically what I'm looking for is Wall outlet > old computer PSU > extension cord.
Thought this would be pretty easy, but when I opened up the PSU I have green/yellow, blue, and brown wires coming off the leads. How can I determine which of these is hot. Also, for fun: what would happen if I reversed the polarity between there and my extension cord?
I'm just kind of messing around with stupid, cheap projects for now, are there any other resources for someone looking to understand basic electric and wiring?
