What is the positive wire?
What is the Positive Wire? The positive wire, also commonly called the hot wire, will typically be black in color. It is the source of the electricity. Whenever working on the positive wire, it is critical that the power is removed, and proper safety precautions are taken.
How can you tell which wire is positive?
If using a two-prong voltage tester, place one lead against the metal box or the ground wire (an exposed, solid copper wire inside the box) and the other against the exposed wire you are testing. If the tester lights up, or shows 120 volts, you have found the positive wire.
What wires go together?

Which color wire is ground?
green
According to Mark Dawson, chief operating officer of Mister Sparky, “green insulated wires are used for grounding.” Green is the most common ground wire color, but “green-yellow” (green wire with a yellow stripe) and “bare” wire (copper wire without colored insulation) can also be used.
What happens if you connect white wire to black wire?
If you see both sides connected together, it means it’s a switch loop. The white wire that’s connected to the black wire carries power to the switch. And the black wire that’s in the same cable carries back that switched power to the outlet. But keep in mind what you should do when the wires are connected.
