Electrons move from the source, through the load and back to the source?

Question

WHERE DOES THE ELECTRON CAME FROM

IN THE THEORY OF ELECTRICITY

Answer 1

The electrons in the outer shell of a metallic atom are mobile. That means it takes very little energy to remove an electron or to add an extra one. If you add some electrons to one end of a copper wire, the atoms at that end will contain excess electrons. The electric field created by those electrons will cause some to move to a neighboring atom. This migration continues until the electric field is nearly uniform over the entire wire, since that is the state of lowest energy. If you continue to provide excess electrons at one end of the wire and remove electrons from the other end, you will have an electric current through the wire.

Imagine a bucket brigade where everyone starts with one bucket of water. Feed buckets into one end and remove buckets from the other end. When someone in the middle gets an extra bucket, he may hold on to it or he may pass one on. But if he is handed a third bucket, he must pass one on before he can take the new one. When he gets an extra bucket, you never know whether he will pass the new bucket on or keep the new one and pass and old one. Any individual electron leaving the source might not return to the source, but generally the same number will return as left.

Answer 2

If you ever imagine that a stable atom shall have the balance number in terms of proton and electron. Now, imagine during the current flow, meaning electrons from source moving into the cables, causing electrons from the cable moving or jumping from one atom to another, and thus this electron actually carrying electrical amps.

This is how the it works.

Answer 3

Electrons come from the Atoms of the material connected between the source to the load back to the source.
(The "Source" has to have a "Differential" of electrons built up on the negative terminal to supply the "Electromotive Force" that results in current flow, before you can have current flow. This can be provided by a chemical process such as a battery or a Electro-Magnetic force as in a power supply.)

Atoms are made of: Electrons, Protons and Neutrons 8-)

Usually "Copper" wire is used in electrical circuits due to it's inherent property as a "Conductor". In other words: it has loose electrons in its outer electron shell that can more easily be pressured by the "Electromotive Force - Voltage" to move to the next atom then the next then the next etc. etc. until you have current flow. Look up: Atomic Stucture, Coulomb and Periodic Table.

Answer 4

When electricity flows, electrons move from atom to atom via a voltage potential where atoms at the negative point of a circuit lose electrons creating a cascade effect thoughout the circuit meduim. The positive point of the circuit creates a surplus of electrons to keep the circuit flowing.

Answer 5

Right, electrons flow from negative to positive, from source to source
