To understand what really happens, imagine a very thin wire, one atom thick. Further imagine that we can label these atoms individually, so that a particular very small section of wire looks like -A-B-C-D-.
An electron comes in from the left. That pushes one of atom A's electrons over to atom B, which in turn pushes one of atom B's electrons to atom C, and so on.
In a real wire, the electric impulse... the net flow of electrons... happens at, effectively, the speed of light (in whatever material the wire is made of). However, any individual electron moves at most very slowly through the wire. This slow movement is called the "drift velocity."
In a 3 ampere current flowing through an 18 gauge wire, electrons have a drift velocity of about a meter per hour.

Why electron travel through the vacuum and not travel through the air?
how electron move in vacuum and not move in air
In a circuit electrons travel in?
The Electron Cloud
What determines the current in each branch of a parallel circuit?
The resistance of the component on that branch of the circuit, if the resistance is higher less of a proportion of the total current of the circuit will travel through that branch, however, if the resistance is low a higher proportion of the current will travel through that branch of the circuit. The voltage through each branch stays the same.
What is a material that does not let electrons travel through it?
Generally speaking, a material that does not let electrons travel through it, a material that has a very high resistance to electron flow (electric current), is called an insulator.
Which travels fastest through a medium a photon atom sound or electron?
Light (photons) will usually travel fastest.
Why electron travel through the vacuum and not travel through the air?
how electron move in vacuum and not move in air
What is cathode and anode?
cathode is electron negative but anode is positiveAnswerFor electrochemical cells, electrons travel through the external circuit from the anode to the cathode.
In a circuit electrons travel in?

What is closed pathway through which electricity can travel?
a circuit.
What kind of circuit can electricity travel through?
"closed"
What determines the current in each branch of parallel of circuit?
The resistance of the component on that branch of the circuit, if the resistance is higher less of a proportion of the total current of the circuit will travel through that branch, however, if the resistance is low a higher proportion of the current will travel through that branch of the circuit. The voltage through each branch stays the same.

The voltage through each branch stays the same.
Why does not it matter where you measure the current in a simple circuit?
The current measured at any point in a simple circuit will be the same because current is the measure of electron flow through a circuit. The current flowing through any branch of any circuit (or an entire simple circuit) will always be the same at any point.
What is short circuit?
Short circuit is the case when electricity, instead of travel through the design circuit path, jump across an unintended low resistance path and bypass the design circuit.A short circuit is a path for an electric current to travel through where there is very little resistance. This path is often, but not always, through a wire connected directly to a ground, and is often, but not always, unintentional.
Is an open switch in an electrical circuit to prevent current flow?
Yes, an open switch breaks the circuit and prevents electricity flowing through. A closed switch on the other hand completes the circuit and in turn helps electricity travel through the circuit.
What happens when an electric current encounters resistance?
An electron traveling through the wires and loads of the external circuit encounters resistance.
