why earth hole size is biggest in plug point?
Answer Posted / ashli
earthing is provided for protection, ie if the body of an
equipment is in contact with current carrying conductor,
the current has to be bypassed to earth so as to avoid
human from getting electric shock. this is done by earthing
the body of the equipment. by earthing we are providing a
low resistance path.ie any how we need to reduce path
resistance. resistance is inversily proportional to area of
cross section of path. thtz y earth hole size is made
bigger. hope u got the point
