What is the potential difference inside a metal conducting wire?
$begingroup$ @Shanza to elaborate on why the electrons are not free (which I have had to defend on this site before), is that in physics we use "free" to mean no interactions with anything (i.e. no forces acting on the electron). The electrons here will still interact with atoms in the wire, and they are being pushed by the field from the battery. Typically when first
What are the fields produced around a current carrying conductor?
The point is that for maintaining $vec E$ inside wire it requires a variable surface charge density i.e. the quasi-neutrality is destroyed making the wire charged hence a minor $vec E$ is observed outside the wire Yes there is an electric field outside of a current carrying wire, in a direction along the wire axis (i.e. parallel to the

If you connect the poles with a wire, a current will flow, driven by the electric field and the electric field is only inside the wire, outside you will have a magnetic field around the wire. Share Cite
How Current Flows Relative to a Battery: Direction, Function, and
Current flow in a battery occurs due to a chemical reaction inside the battery. This reaction generates free electrons, creating a difference in electric potential. This potential difference, or voltage, drives the electrons towards the positive terminal, producing a continuous flow until the chemical reactants are depleted.
current
Every time you push 6.28x10^18 electrons through the wire, you''ve moved one amp of current. That''s 6.28 billion billion electrons. Fields can''t get going inside the wire, so they stay near the surface, and only jostle the electrons near the surface. For DC, the fields can finally penetrate the whole wire and get everything moving, but for

As this is a stationary circuit, as many electrons are flowing out from the cathode into the wire as are flowing back into the anode. Thus at the battery cathode, electrons flow into the wire replacing those that are moved away by the electron current flow in the wire. At the anode, electrons coming from the wire enter the battery.

6 FAQs about [The current of the wire inside the battery]
What is an electric current in a wire?
In solids, an electric current is the flow of free electrons in one direction. is a flow of charge, and in a wire this will be a flow of electrons. We need two things for an electric current to flow: circuit An electrical circuit is made up of components, which are connected together using wires.
What is the difference between voltage and current in a battery?
The voltage of a battery is synonymous with its electromotive force, or emf. This force is responsible for the flow of charge through the circuit, known as the electric current. battery: A device that produces electricity by a chemical reaction between two substances. current: The time rate of flow of electric charge.
What happens if there is a difference between a battery and a wire?
If the difference is small, little/no current will flow. This holds true for any wire connected between any two terminals, anywhere. However, current more than likely won't (depending upon the age/use of the battery).
Can a current flow in a battery?
Maybe something like "Current flow in batteries?" Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics.
What happens if a battery carries a current?
When a battery or power supply sets up a difference in potential between two parts of a wire, an electric field is created and the electrons respond to that field. In a current-carrying conductor, however, the electrons do not all flow in the same direction.
How does a battery circuit work?
The simplest complete circuit is a piece of wire from one end of a battery to the other. An electric current can flow in the wire from one end of the battery to the other, but nothing useful happens. The wire just gets very hot and the battery loses stored internal energy – it ‘goes flat’ and stops working.
