An electrical current is simply the flow of free electrons in and on the conductors. So they are a bit like water molecules in a garden hose. And like those water molecules the flow of free electrons can be physically impeded by whatever is in or on the electrical conductor.
When a material is a good conductor, the atoms and molecules of that good conductor do not get in the way of the free electrons. They do not resist the flow of those electrons very much. So even with just a low voltage to push the electrons along, the flow, the current of the electrons is high.
But when a material is a bod conductor, the atoms and molecules of that bad conductor do physically get in the way of those free electrons so that they cannot flow freely through the conductor. The resistance is high in a poor conductor. So it takes a relatively higher voltage to push electrons along in a bad conductor...if indeed they can be pushed at all. Some materials are so bad at conducting it's almost impossible to move those electrons along.
Electrons flow through a wire due to an electric potential difference created by a source such as a battery. This potential difference provides the necessary push for electrons to move in a continuous path, creating an electric current. The movement of electrons is essential for powering devices and transferring electrical energy.
Please remember than every object, no matter how good a conductor it is, would have some inherent resistance. Now this resistance arises due to the fact that when too many electrons flow in a conductor which results in some of colliding with each other and the current cannot be conducted fully. This is what causes a resistive effect inside the conductor.

What is it called when electrons flow through a wire?
When electrons flow through a conductor such as a wire, it is called, "Electricity".
What is generated around a wire as electrons flow through the wire?
An electromagnetic field is generated around a wire as electrons flow through it. This field has both electric and magnetic components and is responsible for the transmission of energy along the wire.
How is current carried through a wire?
Current is carried through a wire by the flow of electrons. When a voltage is applied across the wire, electrons move from the negative terminal to the positive terminal, creating an electric current. The movement of electrons creates an electric field along the wire, allowing for the flow of current.
Is voltage the flow of electrons through a wire or a conductor?
Voltage is not the flow of electrons, but rather the force or potential difference that drives the electrons to flow through a wire or conductor. Voltage creates an electric field that pushes or pulls the electrons through the circuit.
Why does a thin wire have more resistance than a thick wire?
A thin wire has more resistance than a thick wire because it has less cross-sectional area for the flow of electrons. This results in more collisions between electrons and the wire's atoms, increasing resistance. Thicker wires allow more electrons to flow through, reducing resistance.
What is it called when electrons flow through a wire?
When electrons flow through a conductor such as a wire, it is called, "Electricity".
What does a turbine spin around to make electrons flow in a wire?
Not around... moving THROUGH a magnetic field forces electrons to flow through a wire.
Howdoes Electricity flow through a wire?
Electricity flow through a wire as a result of the movement of electrons and hols.
Which of these is a metal wire that allows electrons to flow through it?
Copper wire is a common metal wire that allows electrons to flow through it easily due to its high electrical conductivity.
What is generated around a wire as electrons flow through the wire?
An electromagnetic field is generated around a wire as electrons flow through it. This field has both electric and magnetic components and is responsible for the transmission of energy along the wire.
What happens when electricity flow through wires?
Electrons move through the wire

The movement of electrons creates an electric field along the wire, allowing for the flow of current.
What is produced whenever there is a flow of electrons in a wire?
Electric current is the movement of electrons through a conductor.
Is voltage the flow of electrons through a wire or a conductor?
Voltage is not the flow of electrons, but rather the force or potential difference that drives the electrons to flow through a wire or conductor. Voltage creates an electric field that pushes or pulls the electrons through the circuit.
What particle is most important for electricity?
Electricity is the flow of electrons through a wire.
Why does the diameter of a wire affect its resistance in terms of current being a flow of electrons?
Because its bigger, so more electrons can flow through
Why does a thin wire have more resistance than a thick wire?
A thin wire has more resistance than a thick wire because it has less cross-sectional area for the flow of electrons. This results in more collisions between electrons and the wire's atoms, increasing resistance. Thicker wires allow more electrons to flow through, reducing resistance.
