… what distinguishes us from the snakes is our ablility to restrain our use of s's ! Polarisation in dielectrics refers to the phenomenon where the molecules of a dielectric material align themselves in a specific orientation when an external electric field is applied. This results in the material becoming polarized and having a slightly positive and negative charge on opposite ends.
Polarisation occurs in dielectrics because the molecules of these materials are made up of electrically charged particles, such as electrons and protons. When an external electric field is applied, these particles are attracted to the opposite charge and align themselves accordingly, resulting in polarisation.
Polarisation can affect the dielectric material in various ways. It can increase the material's ability to store electric charge, decrease its dielectric constant, and reduce its overall capacitance. It can also cause the material to become slightly electrically conductive, depending on the strength of the applied electric field.
Some common examples of dielectric materials include rubber, glass, paper, plastic, and ceramic. These materials are often used in the construction of electronic components, such as capacitors and insulators, due to their ability to resist the flow of electric current.
Polarisation in dielectrics can be measured using a variety of techniques, including the measurement of electric displacement, capacitance, and dielectric constant. These measurements can provide information about the strength of the polarisation and the material's ability to store electric charge.
