For the flow of Electric Current, the material must contain free electrons.
If there are no free electrons, then to conduct electricity the applied voltage must exceed breakdown voltage.
Plastics under ordinary state does not have free electrons but if high voltage is applied then it can start conducting.
Plastic is an insulator, which means it takes a great deal of electrical force (volts) to force an electron into the conduction band. Plastic is often used to insulate conductors from the surrounding environment for this reason.
The ability of a material to pass an electrical current is called conductivity. Materials with a high conductivity are called conductors and those with a low conductivity insulators.
Metals are conductors although some are better than others. Metals such as silver, copper and aluminum are the best conductors of electricity. Copper is the most widely used conductor. Aluminium is used where its lightness is important. Certain alloys are specifically designed to be less conductive. These low conductivity metals are used to make heating elements, filament light bulbs and wire wound resistors.
Dry wood is an insulator and has in the past been used as electrical insulators.
Plastics also make good insulators. Materials such as PVC, ptfe, kevlar, polyester, polycarbonate and solid nylon are commonly used.
Ceramics, paper, mica, resin bonded paper and fibres are also good insulators.
Most can and do.
Only special metalized plastics can conduct electricity.

Why can't electricity flow through plastic?
Because metal and plastic arent the same materials so metal goes with the flow through static electricity but plastic cant.
How do charged conductors and insulators differ from each other?
Insulators prevent electricity or energy from going through them. Conductors allow electricity/energy to easily pass through.
Explain the difference between conductors semiconductors and insulators?
Metals are good conductors of electricity. Insulators are bad conductors of electricity. Similarly, semiconductor devices are partial conductors of electricity means their conductivity lies between conductors and insulators.
List 5 materials that electricity does not flow through well?
1.rubber 2.glass 3.plastic 4.wood 5.cloths This are some materials that electricity not flow through (I think)
A circuit flow on a open switch?
no because when you close it, the circuit is complete so it lets the electrons pass through
Would electricity be able to pass through wood metal or plastic?
Electricity can pass through metal, since it is a good conductor of electricity. Wood and plastic are not conductive and will typically not allow electricity to pass through them, unless they are damp or have conductive materials present.
What things can electricity pass through?
Electricity can pass through conductive materials such as metals and water. Insulating materials such as rubber and plastic do not allow electricity to pass through them. The ability of a material to conduct electricity is determined by the movement of electrons within the material.
Does a insulator let eletricity pass through?
No, an insulator does not allow electricity to pass through. Insulators have high resistance to the flow of electricity, which prevents the current from passing through them. Examples of insulators include rubber, plastic, and glass.
Will electricity flow through a plastic comb?
No, electricity will not flow through a plastic comb because plastic is an insulator and does not conduct electricity.
What kinds of materials cna electricity not pass through?
Electricity cannot pass through materials that are insulators, such as rubber, plastic, glass, and ceramic. These materials have high resistance to the flow of electric current, preventing electricity from easily passing through them. Metals, on the other hand, are good conductors of electricity and allow electricity to flow through them easily.
What is a material that electricity can flow through called?
Electricity can pass through a wide verity of material that are conductive.
What material allows heat or electricity to pass through it easily Give two examples.?
metal and metal and plastic
How are superconductors different from insulators?
Superconductors are materials that let current or electricity pass through them. Insulators are materials that don't allow current or electricity to pass through them. Superconductors are mostly all metals. Insulators are wood, plastic, and paper.
Is a plastic plate a insulator or conductor?
insulator
What allows electricity to pass through it?
An object which is a conductor allows electricity to pass through it
What is a material that does not let electricity pass-through it?
An insulator is a material that does not allow electricity to pass through it easily. Examples of insulators include rubber, plastic, glass, and ceramics. These materials have high electrical resistance, preventing the flow of electric current.
What is a component that makes it difficult for electricity to pass through?
An insulator is a material that makes it difficult for electricity to pass through because it does not allow the flow of electric current. Insulators have high resistance to the flow of electrons, preventing electricity from easily moving through them. Examples of insulators include rubber, plastic, and glass.
