Divergence, Poisson’s and Laplace equation - Electrical Diary

What is divergence? The divergence of a vector field is a scalar quantity that describes the rate of change of the field with respect to position. It is a measure of how much the field is spreading …

Refractive index and absorption coefficient - Electrical Diary

What is the refractive index? The refractive index (n) of a material is a dimensionless quantity that describes how much light is bent when it passes from one medium to another. The refractive index …

Dielectric materials and Gauss’s law in dielectrics - Electrical Diary

What is Dielectric materials? Dielectric materials are insulating materials that do not conduct electricity. They are used to separate electrical charges and store electrical energy. When an electric…

Electric displacement and its Application in Engineering and Physics - Electrical Diary

What is electric displacement? Electric displacement known as electric flux density is a vector quantity in electromagnetism that represents the flow of electric charge in a dielectric material. It …

Clausius-Mossotti equation for dielectric material - Electrical Diary

What is Clausius-Mossotti equation? The Clausius-Mossotti equation is a relationship between the relative permittivity (εr) of a dielectric material and its molecular polarizability (α). The equation…

Electric polarization , Polarizability and Permittivity - Electrical Diary

What is Electric polarization? Electric polarization refers to the separation of electric charges within a material in response to an external electric field. When an electric field is applied to a m…
