When do we apply an external electric field to a dielectric material?
When we apply an external electric field to a dielectric material, we get the Dielectric Polarization. It is the displacement of charges (positive and negative) upon applying an electric field. The main task of the dielectric polarization is to relate macroscopic properties to microscopic properties.
Why is the induced field in a dielectric never cancelled?
The field in the dielectric is only weakened and never completely cancelled. This is due to the fact that the charges in the dielectric are not free to move beyond a particular distance and as such, these are not displaced to such an extent that the induced field is equal to the applied field.
How are dielectric materials classified in atomic view?
With respect to the atomic view, dielectric materials are classified into two categories. Polar and Non-polar Molecules helps us to understand the dielectric behaviour in an electric field.
How are dielectric materials used in the real world?
Application of Dielectric Properties Dielectrics are used as a capacitor for storing energy. The dielectric material in a transformer is used as an insulator and as a cooling agent. To enhance the performance of a semiconductor device, high permittivity dielectric materials are used.
