House, I need your contribution regarding the questions below:

1) What would happen If +ve terminal of a DC battery is connected to a bulb (using one wire) & another wire coming out from bulb is inserted in the ground (earth) instead of connecting it to the -ve terminal of the battery:
a) Would the bulb glow?
b) If yes, does it mean electrons in the wire flow into the earth?
c) If no, would it glow if the -ve terminal of the battery is connected to
the ground?

2) Could you account for the electrons that enter the ground as a result of:
a) connection of the neutral of electric source and drain to a ground?
b) Short circuit fault to a ground?
c) Surges been directed to the ground?

*please give explanation where necessary.
Thanking you.

No

No. (In regard to question c)

some good questions you've got there, I've never thought of it througly before... But my answers above are definately correct.

As to explaining why,.... I don't know.
I'll also like if someone more knowledgeable answers.

Q1a is no, somebidy just ansad! Now, can you climb sheraton hotel in Abuja and come down from control tower of Abuja airport? even though they are both rooted on the same ground!
To the other question, remeber dat the electric station is also conectd to earth, so in effect, nothing really changed the electrons do not go anywhere, but they go round in circle.The overall charge of the earth never change(law of conservation of charge).
