Question

Is Earth a conductor?

Answer 1

Step 1: Explanation:

1. Conductors are materials that allow an electric current to flow without resistance. Some examples include copper, silver, and gold.
2. They facilitate the movement of electrons from atom to atom while conducting electricity.
3. Let us now discuss whether the earth is a conductor or not. It is concluded that the earth is also a conductor as it allows the flow of electricity.

Step 2: Reasons:

1. It is possible to compare the various potentials with the Earth's constant reference potential.
2. To have a reliable zero-voltage reference level, an electrically grounded system must have an accurate current-carrying capability.
3. A "ground" is generally thought of in electrical circuit theory as an infinite source or sink of charge, capable of absorbing an indefinite amount of current without affecting its capacitance.
4. The zero potential estimates no longer apply where there is a true ground connection or where there is significant resistance to earth.

Hence, the earth is a good conductor.
