Earthing is defined as “the process in which the instantaneous discharge of the electrical energy takes place by transferring charges directly to the earth through low resistance wire.” Low resistance earthing wire is chosen to provide the least resistance path for leakage of fault current.
Have you ever experienced a mild shock when you touch certain appliances while in operating condition? Sometimes these shocks can be dangerous and can lead to major hazards. To avoid mishappenings, it is always advisable to have a proper earthing done to the building. This process of sharing the charges with the earth is called earthing. Earthing is a simple way for the leakage of current and hence protects the devices from electrical damage. Grounding is also a safety process that protects the entire power system from malfunctioning and is mainly used to balance the load when the electric system overloads.

Hi sister,sorry for late replying your message,my examwas good,SST paper was very lengthy andI was not ableto complete last part of last questionofsectionD,fortunately that was of only 1mark. My SST paper was divided into 5sections:-
Section A -Objective
Section B -60-80words question answers
Section C -100-120words question answers
Section D -Sourcebased question answers
Section E -Map
Now I have Science exam sister and I am preparing for that.
