Question

Which color is used for earth wire?
(a) Green
(b) Yellow
(c) Both of these
(d) None of these

Answer 1

Hint: If we look around us then we will find that all types of earth related things are of green color. Some earth relation is done by yellow color as well. Wires will be green along with a yellow strip in it are also available.

Complete answer:
Mostly we will see that the type of wires formation as RGB type which means as red-green-blue type. The green one as well yellow color is used as Earth’s wire. This is because the green and yellow type wires are for grounding purposes or we can say earthen purposes. Green colored wires are used in an electric circuit for grounding. It is important for the green wire to be connected to the green wire or to ground only. It is specific for ground based circuits. We will never find such green colored wires in fans or lights. This is because it has such types of functions which are only acceptable for grounding. But any socket like AC, TV or microwave type objects raise green wires as well in them.

So, the correct answer is “Option C”.

Additional Information:
It should never be exposed freely, or if its temperature is hot then it will create problems for the ones who are touching it without precautions or with bare hands once its circuit is on. It mostly never gives shock if it is properly connected to a circuit. But if such wire creates current then this means that the wire is not functioning properly or it is not connected properly because it is made for ground purposes. If it creates current then, it will be a problem.

Note:
One can easily understand the color of the ground wire if one knows the usage of it. This means that most earth related objects have a green sign in them. For example there is most of the time a green strip in our daily toothpaste which lets us know that it is made up of earthly components. Similar to this, any wire which is earth related is colored as green. There are basically three types of earth wires. One which is totally green, the other one which is green along with a yellow stripe and if not coated as green then it will be a free copper wire which is dangerous.
