Give you an examples of conductor?
A conductor is any substance that allows electricity to flow through it easily usually because of the presence of free electrons, that include copper, silver and aluminium and Mercury. Generally, metals are considered to be good conductors. By: Student of Technological University of the philippines
What is electrons contribution to electricity?
flow of free electrons produce electric current
How does electrcity flow?
By movement of free electrons in conductors
What is the difference of poor conductors and insulators of electricity?
Current is the rate of flow of charges. More free electron means more current in conductor.Conductor means element that allows electrons to follow through them easily. Insulator means element that does not allow electrons to flow at all. Conductor like copper atom; has free electrons that flow easily within the conductor. On the othe hand insulators like rubber; does not have any free elctrons. That's why insulators are poor conductor of electricity.
What is a substance that allows heat or electricity to pass through?
A conductor is a substance that allows heat or electricity to pass through. A few examples of conductors are:WaterMetalAir (although not a good conductor is still a conductor)graphiteSalts and solutions of saltsPlasma (ionized gas)Vacuum that contains free electrons or ions
What would be explainable of a good conductor?
It allows the free flow of electrons.
Why does metal conduct electricity?
metal conducts electricity because it allows electrons to move freely as well as it has free electrons, unlike insulators(non-metals) which do not have free electrons. When the electrons are allowed to move freely in a substance, it is a good conductor and allows electric charge to flow.
How is a conducting substance different from an insulating substance?
A conductor has more free electrons at the outer shell (valence) of its atoms. These free electrons move when an electric current is applied across the substance. Insulators, on the other hand, do not have as many free electrons and will take a stronger amount of energy for it to conduct the flow of electrons. In the real world, there are very few real insulators since lightning can flow across anything if the right circumstance exist.
Is a substance that inhibits or stops the flow of free elections?
A dielectric, insulator or insulation Is a substance that inhibits or stops the flow of free elections
How are conductor and insulator alike?
They are not alike at all. A conductor allows for the free passage of electrons throughout its body, while an insulator does not allow electrons to flow through its body.

Why metals good electrical conductors?
In their regular (lattice) structure, metals have a sea of free electrons. This allows the electrons to flow through the metal at will and this is what makes metals good conductors of electricity (and heat).Their mobile electrons
Does current need free electrons for it to flow?
yes it need ion to flow
How many valence electrons does insulator have?
It is not the number of valence electrons that an insulator has that is important. It is the way the valence electrons are "arranged" in the structure of the material that matters. If not all the valence electrons of a substance are "involved" in the structure of the material, then these electrons are said to be free electrons. They move about in the substance, and are free to contribute to electron flow. The metals are examples. In contrast with this, if all the electrons are bound up in a material, they are not free to support current flow, and the material is said to be an insulator. Said another way, if the valence electrons in a material are in a Fermi energy level that overlaps the conduction band for that material, the material is a conductor. In an insulator, the valence electrons are all in Fermi energy levels that are below the conduction band for that material, and it is an insulator. Applying a voltage to an insulator will not "lift" the valence electrons up into the conduction band to allow them to support current flow.
