Detailed explanation-1: -Objects with an excess of charge-either positive or negative-can have this charge removed by a process known as grounding. Grounding is the process of removing the excess charge on an object by means of the transfer of electrons between it and another object of substantial size.
Detailed explanation-2: -A conducting object is said to be grounded if it is connected to the Earth through a conductor. Grounding allows transfer of charge to and from the earth’s large reservoir. Objects can be charged by contact with another charged object and obtain the same sign charge.
Detailed explanation-3: -When a charged object is connected to earth by means of a conducting wire the charge from the object flows to the earth and the object becomes electrical neutral, this process as called Earthing or Grounding.
Detailed explanation-4: -Earth acts as a ground of zero potential. So when a positively charged conductor is connected to the earth, positive charge flows into the earth and as a result, electrons flow from earth to the conductor.
