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.

residential-usually black. sometimes red or blue. White is your neutral and green or bare copper is ground. And when you see a black wire spliced to a white wire, this indicates a switch leg usually.
Brown = live (hot) - (equivalent to Red wire) Blue = neutral - (equivalent to the Black wire) Yellow and green = earth. --------------------------------------------------------------------------- However never rely on the wire colors - you should test the wires with a meter to be sure that the person before you has not made a mistake further back in the wiring.
Another homework question? The wires could be Hot or Live, Neutral and Ground.
eletrical wire has 3 specif colour coding. As live wire ,neutral wire,earth wire. 1.live - red 2.neutral-black 3.earth - green. These are the specific color coding of eletrical wire.
The only designated colors in electrical wiring in North America are White as a neutral and Green as a ground wire. All other colors can be used as live wires. There are specific colors designated by the electrical code for phase wiring.Answer for European SystemsThe relevant regulations define all conductors, other than the protective (earth/ground) conductor, as 'live' conductors. In Europe, the line conductor has a nominal potential of 230 V with respect to the neutral conductor.In Europe, the the three line conductors of a three-phase system are identified with brown, black, and grey insulation, respectively. For single-phase systems, brown is normally used. Neutral conductors are identified using blue insulation, and protective (earth/ground) conductors are identified using green/yellow stripedinsulation.
In the US older 2-conductor house wire has a white-insulated and a black-insulated wire. The white wire is the neutral and the black is the hot wire. Newer house wire has a third bare copper wire to serve as the ground wire. Insulated ground wire has a green jacketing on it. Red wires are for switch legs. You want to be sure that whomever did the wiring didn't flip the colors around. You can do this by checking the fuse or breaker box - the white or neutral wires should all run to the multi-neutral ground bus bar and the black or hot wires should each go to their respective circuit breakers or fuse sockets. On your switches and recepticals, the gold screw is for the black, or hot wire, and the silver screw is for the neutral. The green screw would be for the ground wire. Mostly, use a qualified electrician to do any work unless you are quite handy, have all necessary tools and fully aware of all safety precautions and code requirements that may exist where you live.
In the USA we call it the ground. If there is a cross in the wires from hot to common the ground or earth wire will give the electricity an easier path to the ground instead of going through a live person. The earth is attached in the main box to a copper rod hammered into the ground. This makes it easier for electricity to get to the ground.
Electricity seeks the fastest path to the ground. If a live wire happens to touch the ground most often the line will "ground out" and cause the electricity to flow into the ground. This can cause breaks and circuits to break and cause other electrical malfunctions.

in the ground
hi the ground wires are white the live depends on if its been wired by another but usually black or brown
eletrical wire has 3 specif colour coding. As live wire ,neutral wire,earth wire. 1.live - red 2.neutral-black 3.earth - green. These are the specific color coding of eletrical wire.
If you mean the wires in the battery charger's household AC power cord the three wires are "Hot" or "Live", "Neutral", "Ground".

Europe follows the IEC colour code that was adopted also by the UK in 2004: Single-phase: Earth: yellow and green, Neutral: blue, Live: brown. Three-phase: Earth: yellow and green, Neutral: blue, Live: brown, black, grey. In some cables the Earth wire is bare copper which should be fitted with yellow and green sleeving at its terminations.
