It is a material that resists electrical current at eminent.
Use the insulators and conductors or insulators silver ceramic.
The insulator is a material that retards the flow of electricity.
Conductors insulators and semiconductors conductors an electric current is produced when free electrons move from one atom to the next.
This is an ideal quality in many cases strong insulators are often used to coat or provide a barrier between conductors to keep electric currents under control.
Plastic is a good insulator and it finds its use in making a number of things.
Insulators oppose electrical current and make poor conductors due to lack of free electrons.
The most effective electrical insulators are.
Rubber is a common material used in making tyres fire resistant clothes and slippers.
Glass air plastic rubber porcelain and wood.
Glass is the best insulator as it has the highest resistivity.
Very little electric current will flow through it under the influence of an electric field this contrasts with other materials semiconductors and conductors which conduct electric current more easily.
Copper is the most common metal used for conductors and is relatively inexpensive.
There are different insulators used in the electrical and electronic component and assemblies.
Electric charges do not flow freely through insulators.
An electrical insulator is a material in which the electron does not flow freely or the atom of the insulator have tightly bound electrons whose internal electric charges do not flow freely.
Those substances which offer least resistance to flow of electrons or electricity are called conductors and the substances offering high resistance to the movement of electrons are called insulator.

Copper aluminum gold and silver water and other metals.
Some of the insulators are porcelain plastic ceramic polymer etc.
Some common conductors are.
The following table gives the properties of the different insulating materials used.
10 electrical insulators.
Copper silver aluminum zinc brass and iron are considered good contors.
Thus conductors and insulators may be defined as under.
Some common insulators are.
