Ok, so, when you plug something into an electrical socket, there are 2 metal prongs. On the prongs, there is 1 hole. Why?

The holes on some plugs are for locking devices that keep the plug out of outlets when it is not safe to plug the in, or keep them in outlets when it is important they stay in (Like a heart monitor in a hospital or something). Also they make it easier to attach wire to the plug if necessary.
If you were referring to the outlet holes, one is for the charge, one is for the neutral, and one is for the ground.
I hope this was helpful.

If you don't want someone to use it you can put a little pad lock
on it. (also known as a lockout)
