1. The Flow of Electrons:

* The earth acts as a vast reservoir of electrons.

* Since the conductor has a positive charge (meaning a deficiency of electrons), electrons will flow from the earth to the conductor.

* This flow continues until the conductor reaches the same electrical potential as the earth, which is considered to be zero potential.

2. Neutralization of Charge:

* As electrons flow into the conductor, they combine with the positive charges present, effectively neutralizing the excess positive charge.

* The conductor will now have a neutral charge.

3. The Earth's Vastness:

* The earth is so large that the flow of electrons from the earth to the conductor does not significantly alter the earth's overall charge.

* This is why we can consider the earth to be an infinite source of electrons for the purpose of grounding.

In essence, earthing a positively charged conductor provides a path for electrons to flow from the earth to the conductor, neutralizing its positive charge.

Why do we do this?

* Safety: Earthing prevents the accumulation of static charges, which can lead to electrical shocks or sparks.

* Protection of Equipment: In electrical circuits, grounding ensures that any excess charge is safely directed to the earth, preventing damage to sensitive equipment.
