What is an insulator? Give 5 examples of an insulator!

Insulator are materials that do not conduct electricity, for example: rubber, wood, plastic, glass, oil

 

 

Discussion of Isolator Details

Based on the conductivity properties, materials can be classified into:

conductor (always conductive), such as copper wire
insulator (always blocking the flow of electricity), e.g. rubber
semiconductors (which can conduct or inhibit current depending on certain conditions), such as silicon

This conductive property is called electrical conductivity.

Electric current is the flow of electrons from objects with high potential to objects with low potential. This flow of electrons lasts until the difference in voltage between them disappears.

In flow, the flow is carried out through a conducting medium which has many electron free.

Metal is one type of this material, as we know metals such as iron, copper and gold are types of objects that can conduct electricity. Metal atoms have an outermost electron that is not bonded to any of the atoms because the metallic bonds between the atoms form a "sea of loose electrons".

These conductors may also be filled with ions moving in a solution, such as a solution of sulfuric acid in a battery or a solution of table salt.

In contrast, there are no such free electrons in materials made of non-metallic elements (such as oxygen gas) or compounds with covalent bonds (such as oil, rubber, and pure water). These materials are called insulators.
