The earth wire connects the metal frame of the electrical appliances to the ground. The convention is to have green colour for earth wires. The purpose of earthing is that in case of an insulation failure in some appliance, this wire connected to the metal body will provide a path for the current to flow on the ground. In absence of earth wire, this fault current would have flown through the body of the operator, causing electrical shock.

Why do you need an earth wire in a plug?
The Earth wire is there to earth electrical devices that are not double insulated. If there was to be a malfunction in the appliance then you can get a really bad shock if an earth wire is not present. If there is any free electricity roming around then the earth wire will send it down to earth and to the main power station closest to the area instead of through your body. s aged 15
What function is performed by earth atmosphere?
Earth's temperature is raised and moderated by trapping in heat.
which function is performed by earth’s atmosphere?
Earth's temperature is raised and moderated by trapping in heat.
Which part of the of a washing machine should the earth wire be connected to?
the metal casing around it :)
What is the earth wire for in a plug?
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.
When charge are able to flow directly from the circuit into Earth a ciruit electrically?
That is what the Earth wire does. Normally it does not carry current but it has this important safety function.
What is difference between nutral and earth wire?
A neutral wire provides a return path for the hot lead while an earth or "ground" wire is provided as a safety function only that is not normally intended to carry current except for the purpose of operator protection.
Can you connect a 6mm earth wire to a 2.5 mm earth wire?
A 6 mm earth wire can be used to replace a 2.5 mm earth wire, but if there is an existing 6 mm earth wire it must be 6 mm all the way to the earth, and not replaced by a smaller wire between it and the earth connection.
Wire that discharges excess electricity to the earth?
It is the earth wire
When you connect earth wire in ceiling light does not work when connecting earth from light direct to earth wire coming from ceiling trips out when take earth wire out light works?
By earth wire I am assuming you mean the bare wire and that a black and white wire are connected to the light. If when you connect the earth wire and breaker trips then there is a short between black and earth. It could be a bad ground connection, an internal short in the light fixture where black wire "hot" is connected to metal on the fixture through a nick in wire.
What does green wire indicates?
Earth wire
How you provide earthing by three pin plug?
The three pins are live, neutral and earth. The live and neutral carry the current, and the earth should carry no current. Its function is to connect together the external parts of all pieces of equipment so that it's impossible to get a shock by touching two items at once. Another function is to connect the external parts to an earth rod and to the gas and water pipes in the property. Another function is that if an internal fault allows a live wire to touch the case, enough current will flow to blow the fuse or trip the circuit breaker. So in different ways the earth pin/wire provides an important safety feature. In Europe the earth wire is coloured green and yellow.
What are the function of wire stripper?
They are for stripping the insulation off electrical wire.
Why is your earth wire is glowing on the live circuit?
In the visible spectrum or the infrared? Either way, if your earth wire is glowing you have a problem. Your earth wire is not intended as a current carrying wire. If the wire is loaded to the point that it glows then your circuit/breaker is not wired correctly and the earth wire is being used as an unintended path and is a hazard. Earth wires are not sized properly to carry current.
What is the third green wire on an electric drill is the wire?
it is the earth wire
How can earth wire prevent electric shocking?
large current flows from live to earth wire.
When an electrical earthing wire is showing live what is the problem?
earth wire not cnnected from main earth
