A ground to earth completes an electrical circuit in some cases. The wire is called the ground or grounding wire, and often has green insulation.

What happens in a plug if there's no earth wire?
it protects you from getting electric shocks or being electrocuted.
How does a hot wire emit electrons?
a hot wire emits electrons just like any other wire would. It is through the flow of electricity. Its the exact same thing. Good question though
What is the purpose of the wire that drags ground under shopping carts at Walmart and Target?
It's supposed to be the ground wire...to keep the shopping carts from building up static electricity.
What is the colour cables to lambda sensor for white heater grey earth?
the two white wires. one is for lambda heater.along with the grey wire.the other white wire is lambda itself it gets its earth from the exhaust. and the black wire is the signal wire
How does the resistance differ between long and short wires?
Generally, the longer the wire, the more electricity will be lost because of resistance.
Wire that discharges excess electricity to the earth?
It is the earth wire
What is a wire that discharges excess electricity to the earth?
earth
What is a wire that discharges electricity to the earth?
That would be called a ground wire.
Why you get shock when touching uncovered wire?
You can be shocked because that the wire is passing electricity and that its moving around. Your body has electricity in them and when touched the electricity are moved and you get shocked
What are the advantages of an earthwire?
earth wire is used to give us protection against electricity if shocked.
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 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.
Where does excess electricty go?
There is no excess "electricity". Excess (or a deficit of) electrons end up as a static charge. "Extra" current in a wire occurs at a phase angle other than the phase of the applied voltage, but this energy is largely recovered (being essentially "imaginary power").
Why don't birds get electricuted while on a electric line?
To get electrocuted you need to complete an electrical circuit. That takes two wires or a wire and an "earth". A bird on a wire is not making a connection to a second wire or to the earth. Therefore no electricity flows and they are perfectly safe.
Can a wire produce electricity by itself?
You coil a wire and pass it through a magnetic field you will produce electricity.
How can grounding can offer protection from electric discharges?
A: That relates to the fact that humans are earth bound. The sky is above earth and it contains potential this potential will discharge to whatever point has the lower resistance like earth. So grounding an edifice will guarantee that the discharge will follow the wire as opposed to humans or gas tanks
Howdoes Electricity flow through a wire?
Electricity flow through a wire as a result of the movement of electrons and hols.
