How electron pass when current flow through different metal conductor joint each other?

the joint will show a slight misalignment of the conduction band: it's like a small water fall, if you compare electrons to the water flowing in a river.
This effect will always generate a contact resistance (Cu-Cu ~50-300uOhm, Ag-Cu ~10uOhm to give you an idea) and a small potential barrier (negligible for metal-metal interface).

What happens to metals as they conduct electricity?
The electrons in a conductor will support the movement of electric current. A conductor is defined as a material with a number of electrons in its makeup that are actually in what is called the conduction band. The conduction band is an energy level where electrons must be to permit conduction in a material. If the minimum energy in the conduction band in a material is such that a lot of electrons in that material are already at or above that level, then these electrons will be available to support current flow. Remember that electron current flow is moving electrons, and it is not about sending an electron into a conductor, like a wire, at one end and getting that same electron out at the other. It is about sending a bunch of them in at one end, and all the electrons already in the conductor move over and a bunch come out the other end. The electrons already in the conduction band within the conductor support current flow in this way.
When an electric charge moves through a conductor there is an electric in the conductor?
current
What does a conductor do in a magnetic field when current is suddenly passed through it?
the conductor has to be moved.
When electric current flows through a metal wire?
current flows through the conductor due to the motion of the free charge carriers present in it. The more charge carriers present in the conductor, the more current flow through that conductor. No free carriers present in the insulator and hence no current flows through insulator. thus..free charge carriers causes the current flows through the conductor.
How far can electrical current travel through a body of water?
There is no length because as long as it is a conductor an electrical current can go through
How is conductor different from insulator?
A conductor has a free electron to which current can pass through
How is conductor different from an insulator?
A conductor has a free electron to which current can pass through
What is an electron current?
the flow of electrons through a conductor
What is electron current?
the flow of electrons through a conductor
Is it true that when an electric current flows through a long conductor each free electron moves through a relatively short distance?
It is not true that when electric current flows through a long conductor each electron moves through a relative short distance because electric current is the continues flow of electrons.
What do you call the movement of electrons through a conductor?
Electron flow; also known as electrical current.
Why does current flow through a conductor explain?
The valence band electrons in a conductor are free to drift as an electron gas filling the conductor, in response to an electrical field imposed across the conductor/
What is a flow of electrons moving along a wire or conductor?
An electric current. <<>> The term used for the flow of electrons through a conductor is amperage.
When an electric current moves through a long conductor each electron moves?
The free electrons moves through a relatively short distance.
When an electronic current flows through a long conductor each free electron?
The free electrons moves through a relatively short distance.
What happens to the electrons in a conductor when there is a potential difference between the conductor's ends?
The free electrons in a conductor will, when a difference of potential (voltage) is applied at its ends, participate in electron current flow (or just current, if you prefer). The voltage applied to the conductor will drive current through the conductor, and the free electrons will support current flow. These electrons will actually move through the conductor. As electrons are driven into one end of the conductor, the free electrons "shift over" and electrons stream out the other end of the conductor. This is the essence of current flow in conductors.
When an electric current flows through a long-conductor each free electron moves?
The free electrons moves through a relatively short distance.
