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.
What else can I help you with?
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.
How does electricity flow through a wire?
Electricity flows through a wire when electrons move from atom to atom. This movement creates an electric current, which is the flow of electric charge. The flow of electrons is driven by a voltage difference, or potential difference, between the two ends of the wire.
Is voltage the flow of electrons through a wire or a conductor?
The flow of electrons through a conductor is called electric current.The voltage is the 'pressure' or difference in electric potential between theends of the wire, that encourages each electron to try to move closer toone end and farther away from the other end.
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

Where do moving electrons come from when making an electromagnet?
Moving electrons in an electromagnet come from the flow of electric current through a wire or coil of wire.
What particle is most important for electricity?
Electricity is the flow of electrons through a wire.
