What is the flow of electrons through a material called?
Electricity".insulatorInsulatorinsulatorCurrent
Can electricity pass through mercury?
yes, passage of electricity depends on the structure of material at atomic level since electricity is nothing but flow of charge, any material which acquires charge(electrons or ions) on it, can allow passage of electricity. mercury being a metal, contains free electrons which is responsible for passage of electricity
What materials allow electricity to flow freely?
Because of freely moving of electrons in the material
Electricity that does not flow?
What you are referring to is called static electricity. It is defined as the accumulation of electric charge on the surface of a non-conducting (insulating) material. It is generally produced by friction or by electrostatic induction.
Where does static electricity occur?
when 2 bodies are rubbed together,electrons are transferred this causes static electricity.

How does electricity get to place to place?
Electricity travels in electrons through conductive material. The way that electricity can get from point to point is by traveling through wire-enclosed metallic material that is most accepting to the electrons. The result is electricity from a far distance from a main power plant which generates the electricity.
Is metal a conductor of electricity?
For a material to conduct electricity, it must have free movable electric charges, such as free electrons or free ions, in order to 'carry' electricity. In the case of metals, there is a 'sea' of delocalized electrons. These free electrons can 'carry' the electricity, and thus, it is a conductor.

Why can't electricity go through rubber?
Rubber is what is known as an electrical insulator. The difference between insulators, which block the flow of electricity, and conductors, which permit the flow of electricity, lies in the availability of mobile electrons in the material in question. Electricity is composed of moving electrons. Some materials, such as metals, contain electrons that are easily moved, hence electric currents move easily in those materials. If a material does not have electrons that are easily moved, then it resists the flow of electrons.

A conductor differs from an insulator in that a conductor is an?
A conductor is a material that has one or a few electrons in the outer shell of its atoms. These electrons are easily knocked loose, or are already moving about in the material. When a voltage is applied to a conductor, these electrons are repelled by the negative polarity and attracted by the positive polarity. Their movement is called "current". a conductor is a material that transports electrons and electricity can pass through it, metals are good conductors. a insulator is something that is a barrier to electrons and can not pass electricity, rubber is a good insulator.
Why cant conductors generate static electricity when rubbed together?
Static electricity causes electrons to move from one material to the other. In an insulator, these electrons can't flow back to equalise the charges, whereas in a conductor they can; so whilst they could conceivably generate static electricity, it would be lost as quickly as it was made.
What are electricity principals?
Electricity is the flow of electric current through the conductor. Electric current takes the form of free electrons that transfer from one atom to the other. Thus the more free electrons a material has, the better it conducts.
