Why is the earth pin in a 3-pin plug the longest and the
thickest?
Answer Posted / ajay
Resistance =pl/a
where a is "area".
And area is directly propotional to lenght and thickness.
so if the area is greater mean resistance is less.
and resistance is inversly proptional to current.
so it will act as low resistance path for neutral current.
