Red wires are used to help to identify them from other wiring which has other colors.
Red-colored wires are used in many different electrical circuits, both within and supplying power to all kinds of electrical/electronic equipment. Such equipment may used in many different ways: some may be portable and designed to be worn or carried by people, such as music players, radios, phones, etc. Other types of electrical and electronic equipment may be much larger and heavier and designed for use in buildings, industrial sites, open land sites, mines, vehicles, boats and ships, aircraft, space rockets, satellites and space stations, etc.
You must first understand the technical details of a piece of equipment or a circuit in which a particular wire that is colored red is being used before you can start to understand the purpose of that wire. Even then it is wise not to assume that the wire is carrying any particular voltage, current or signal until you have taken the necessary steps to measure what it is carrying safely and correctly.

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.

red is positive and black is neutral...if the wires are red and black.
Pilots flying in an airplane can't see the wires and might crash into them. The red balls act like flags to alert the pilots that the wires are there. Good question!
