ok so this wall power outlet has four wires coming out of it, i can tell a single wire apart, i have no way of knowing they are all black with insulation. i took the outlet out because it wasnt working
i just bought a multimeter today but the instructions really suck it wasnt expensive though just not sure how to use the damn thing
i got all the power shut off in this house so im not working on live wires like a moron
on the back of the outlet there are no identification markers as to where the wires should be hooked into the screws on the outlet ( i realize that the older outlets have no identification markers for where the wires should go)
i just dont know how the hell to identify each wire, and the the other two outlets have 4 wires in them each (they are both outlets like this

thanks for the help
ive been reading alot latley studying the MIT courses in the electricity and magnetism very good stuff a shitload of equations on coulombs section of electricity now, havent read any eric dollards stuff latley just checking out what standard science is saying im on lecture 3 its rather fascinating when you have one charge thats negative and one charge thats positive they attract , and two positive charges will repell (this is true electrostatics meaning action at a distance)
lets say billy falcon is negative charged and wilson f is also negative charge they will repell via the
electric field lines of force now the fascinating part is there is much debate on what these lines of force consist of that are moving billy and wilson away from each other, many claim its photons, no real consice answer
if you want to know what i know (but dont even yet know how to identify the wires or use a multimeter yet

) check these videos hope you will find them interesting
this is like free education of the highest order, god like knowledge for free
