Difference between Earthing and Grounding

The major difference between earthing and grounding is a difference that is important to remember. Earthing can simply be defined as the process of protecting against unwarranted spikes and bouts of electricity that can cause damage to life and property. Therefore it is important to remember these key differences between the two. One needs to understand that they both are referring to the same process. A deeper understanding of Electric Potential can prove useful in this method.

Difference between Earthing and Grounding

Grounding is similar to Earthing, by which insulation against accidental currents are achieved. The main live wire is connected to a power supply to power an appliance, however the other portion of the wire is led under the earth. This is done in case of an accidental cut in the circuit, to avoid overloading and other dangerous side effects.

Earthing

Grounding

This method protects the human being from electrocuted.

This method protects the entire power system from malfunctioning.

Earthing contains zero potential.

Grounding does not possess any zero potential.

The earth wire used is green in color.

The wire used for grounding is black in color

Earthing is primarily used to avoid shocking the humans.

Grounding is primarily used for unbalancing when the electric system overloads.

Earthing is  located under the earth pit, between the equipment body underground.

It is located between the neutral of the equipment being used and the ground.

Practise This Question

Water is filled up to a height h in a beaker of radius R. The density of water is ρ, the surface tension of water is T and the atmospheric pressure is P0. Consider a vertical section ABCD of the water column through a diameter of the beaker. The force on water on one side of the section by water on the other side of this section has magnitude:
