What Does dielectric Mean
Dielectric is an adjective used to describe a material that, due to its characteristics, is not a good conductor of electricity . Its electrical conductivity, therefore, is low.
It should be remembered that electricity is called the force manifested through the rejection or attraction between charged particles. The form of energy that is based on this force is also known as electricity.
The electrical conductivity is the ability of a body to allow the passage of electric current therethrough. Good drivers, in this way, do not obstruct that passage, unlike what happens with bad drivers.
Returning to the idea of dielectric, this is how the element that is a bad electrical conductor is mentioned . This means that the electric current finds great difficulties to pass through a material that is dielectric.
Thanks to their properties, dielectric materials function as insulators . Among them it is possible to name paper , ceramics and glass . Even air is dielectric, as are other gases and also various liquids (such as castor oil ).
It is important to note that the insulating capacity is not infinite. Dielectric bodies resist a maximum value of the electric field intensity is known as rigidity Dielectric : surpassed that mark, the material becomes conductive .
In this sense, it can be stated that dielectric materials have different degrees of permittivity . This refers to the capacity they have for the electric field to establish itself or not.
