Answer Posted / bhupendra rawat
Earthing :- Earthing means to connect the metallic part of the electric appliance or instrument threw a wire having negligible resistance to the huge mass of earth.
There are three types of earthing:-
1:- Pipe earthing:- in this earthing we use a 3-4 inches pipe of negligible resistance.
2:- Plate earthing:- in this earthing we use a Cu. or Al. plate having negligible resistance.
3:- Rod earthing:- this is also called temporary earthing. in this earthing we use a rod of negligible resistance.
and the another end which is underground is surrounded by charcoal or salt.
