Black, Blue and Red are the most common hot wires and White can be hot if it is being used as a switch leg, in residential wiring, but it must be identified as hot by a colored marking tape showing that it is not a neutral.
The only colored wire that should never be used as a hot is Green.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.
IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

No, AC outlets do not have positive and negative terminals like DC outlets. AC outlets have hot and neutral terminals, with the hot being the live current-carrying wire and the neutral being the return path for the current.
No, positive wire and hot wire are not the same. Positive wire typically refers to the wire carrying positive voltage in a DC circuit, while hot wire usually refers to the wire carrying current in an AC circuit. The terms are specific to different types of electrical systems.
An extension cord that you plug into your house is neither positive OR negative. It uses alternating current so there's a live wire and a ground. Only direct currents (like those in cars) have positive and negative. On a two wire extension cord the ribbed side is the neutral. If you look close and it is a moulded plug on the end of the extension cord you will find that the side with the rib is also the same side as the wider blade on the plug. This corresponds to the wide blade hole in the receptacle which is also the neutral side of the receptacle.
There is no positive or negative side on a standard 120V home power outlet, as it provides AC (alternating current) power. The outlet has two power prongs - one is the "hot" wire providing the alternating current, and the other is the "neutral" wire completing the electrical circuit.
The positive wire for the reverse light is typically the one that carries power to the light bulb. It is usually connected to the switch that is activated when the vehicle is put into reverse gear. You can use a multimeter to test which wire is carrying power when the vehicle is in reverse.
Your question is too vague. Please tell us what your trying to wire.
Positive
Yes, that is correct.
If you want to run both coils,you have to wire the positive to positive and negative to negative on your sub,then run a wire from each plug to the amp. Positive to the positive side of the amp and negative to negative side of the amp,(you can run in bridge mode or stereo if your amp can handle the load)
you have to have 2 wires. then you put a wire to the positive side of the battery(+) and the other wire to the negative side of the battery(-). then both other ends to the light bulb one end to the side and one end to the bottom. you have to have 2 wires. then you put a wire to the positive side of the battery(+) and the other wire to the negative side of the battery(-). then both other ends to the light bulb one end to the side and one end to the bottom.
it has something to do with the electrical current pssing through the wires to the battery
the positive side has the fuse
well try to find if one wire has a darker color copper than the other, this would help. or if one side of the wire coat has a white stripe on it, then the stripe indicates it's positive
The red battery wire goes on the positive + battery terminal no matter which side it is on. The black wire goes on the negative - terminal.

take the speaker out and run 2 wires from the speaker one on positive side and one on the negative side the use a 9volt battery and touch one wire to each side the speaker should make a popping sound moving either up or down depending on which wire you have where. if you touch the positive wire on the positive side of the battery it should move out and if reverse should move in. if it does not do anything the speaker is blown.
Should be HOT at one side of the brake light switch
