Why we dont feel the current from Earth wire?

In summary, the Earth wire carries current to the ground, which is a good conductor of electricity. However, the Earth wire only carries current if there is a fault with the equipment, tool, etc. If it is working correctly, the current flow is very brief until the main fuse blows. Therefore, it is unlikely to feel any current from the Earth wire when walking on the ground due to the large surface area of the Earth. However, in the event of a power line touching the ground, it can be dangerous and should be avoided.

The Earth wire carries current to the ground and we walk on the ground and the ground is a good conductor of electricity. So when we walk on the ground then how come we don't feel the current from the Earth wire?

the Earth wire doesn't carry current unless there is a fault with the equipment, tool, etc
and if its working correctly the current flowing in the Earth wire should be very brief till the main fuse blows

if that doesn't answer your question, then you need to be much more clearer about the situation you are referring to

I think you are asking why we don't feel any current on the ground. The Earth is a big place, so the current is dissipated.

Earth/earth wire provides path of much less resistance

As the others said, with normal wiring there are no significant currents in the Earth to be felt.

However, if a power line is knocked down by accident and touches the ground, it can be very dangerous to approach it. Stay 30-50 meters away.
 

1. Why don't we feel the current from the Earth wire?

The Earth wire serves as a safety measure in electrical circuits to prevent electrical shocks. It is connected to the ground, which is a large mass of conducting material. When there is a fault in the circuit, excess current is directed towards the ground through the Earth wire. This prevents the current from passing through our bodies, thus preventing any feeling of electrical shock.

2. If the Earth wire is connected to the ground, why don't we get shocked when we touch it?

The ground is a large mass of conducting material, such as soil or water, which can easily disperse excess current. When we touch the Earth wire, any excess current is quickly directed towards the ground, preventing it from passing through our bodies and causing harm.

3. Why is the Earth wire necessary in electrical circuits?

The Earth wire serves as a safety measure in electrical circuits to prevent electrical shocks. It is connected to the ground, which is a large mass of conducting material. In case of a fault in the circuit, the Earth wire provides a low-resistance path for excess current to flow towards the ground, preventing it from passing through our bodies.

4. Is the Earth wire the same as the neutral wire?

No, the Earth wire and the neutral wire serve different purposes in an electrical circuit. The neutral wire carries the return current from the electrical load back to the source, while the Earth wire is solely used for safety purposes in case of a fault in the circuit.

5. Can we remove the Earth wire from electrical circuits?

No, the Earth wire is a crucial safety measure in electrical circuits and should never be removed. It helps to prevent electrical shocks and protects both humans and appliances from any potential harm. Removing the Earth wire can lead to serious safety hazards and should only be done by trained professionals in certain situations.
