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.

∙ 8y agoPlease 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.
Thnx....

∙ 10y agoElectrons flow in a metal because they are not tightly bound to the atoms - they are relatively free to move. However, a current will only flow if a voltage is apply.

What is it called when electrons flow through a wire?
When electrons flow through a conductor such as a wire, it is called, "Electricity".
Flow of electrons at a given point through wire per second?
current
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.
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.
When a magnet is moved alongside a wire what happenes?
the electrons in the wire begin to flow
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?
conductor
What happens when electricity flow through wires?
Electrons move through the wire
What is produced whenever there is a flow of electrons in a wire?
Electric current is the movement of electrons through a conductor.
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
What particle is most important for electricity?
Electricity is the flow of electrons through a wire.
Flow of electrons at a given point through wire per second?
current
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.
If more electrons were flowing through a wire what would be increased?
If more electrons were flowing through a wire, the thing that would be increased would be the current. This is the flow of the carriers of electrical charges.
What is present when currents flow through a wire?
There must be a Electron flow in that wire. Or Energy in the form of Electric will flow in that wire. Influences that are present are Voltage, Ohms, and Amperes (amps)
