@keyurami,
Key that's a very good q

Maybe because of its size. You can probably change its overall charge just a little bit but because it's so big its average stays pretty much around zero

Let's hear from someone who knows about this sort of thing

The earth, because of its size, contains/is formed by an almost infinite number of atoms. These atoms can accomodate the relatively feeble number of free electrons that constitute electricity, whichever nature.

The natural tendency of free atoms is to stabilize themselves in whatever place they find free on an atom's orbit.

Given the huge choice they have in earth atoms, they will flow there naturaly.

@timur,
Yes, basically, a property which makes something a 'ground' (Earth with the OP's case) is that it does not change its potential regardless of the current that flows in or out - within the limits of operation.
There might be some misunderstanding in the OP's mind. Theoretically, "ground" is just another wire in the circuit, but this necessarily doesn't mean all electrical system will operate fine with no connection to "ground." With single wire earth return, your don't have a circuit if you don't have a ground.

True Enzo; but Key, the earth return isn't very efficient and bears a certain illegal aspect

Split-phase device of course works fine without ground but as I had implied, you just have to have that ground wire to your 120-v light for efficiency snd safety

@dalehileman,
A freudian slip, as you can see by reading my first paragraph.

@timur,
A slip of course Tim but why Freudian

What's sexy about the static charge


Oh, Key, have se been of the slightest help

@dalehileman,
Why you connect it (pun intended) to sex, I wonder:

Wiki wrote:
A Freudian slip, also called parapraxis, is an error in speech, memory, or physical action that is interpreted as occurring due to the interference of some unconscious ("dynamically repressed") subdued wish, conflict, or train of thought.

@timur,
Good one Tim, Yes of course

However in the pop mind Freud is identified with sex
