What is Clausius-Mossotti factor?
The Clausius-Mossotti factor as a function of the frequency of the applied voltage for different dielectric properties of a 10-m-diameter biological cell. ” and are the permittivity and the electrical conductivity of the cell interior. The units of C , G , and are mF=m , kS=m , and S/m, respectively.
What is the use of Clausius-Mossotti equation?
The Clausius-Mossotti equation relates the dielectric constant of a material to the polarisability of its atoms. It finds natural explanation in terms of the (often omitted) delta function in the electric field of an ideal dipole.
What is meant by local field in dielectric deduce Clausius-Mossotti equation?
We define the local field Eloc to be the field felt by one particle (mostly an atom) of the material at its position (x,y,z). The electrical field then is just the (negative) gradient of the potential; E = – ∇V.
Which is Lorentz relation?
A relation between the polarizability α of a molecule and the refractive index n of a substance made up of molecules with this polarizability. The Lorentz-Lorenz equation can be written in the form α=(3/4πN) [(n 2–1/(n 2+2)], where N is the number of molecules per unit volume.
What is Langevin Debye equation?
A formula for the polarizability of a dielectric material or the paramagnetic susceptibility of a magnetic material, in which these quantities are the sum of a temperature-independent contribution and a contribution arising from the partial orientation of permanent electric or magnetic dipole moments which varies …
How is Clausius-Mossotti equation derived?
The Clausius-Mossotti equation can be written in the form α = (3/4πN)/[(ε – 1)/(ε – 2)], where N is the number of molecules per unit volume.
What is meant by dielectric material?
Dielectric, insulating material or a very poor conductor of electric current. When dielectrics are placed in an electric field, practically no current flows in them because, unlike metals, they have no loosely bound, or free, electrons that may drift through the material. Instead, electric polarization occurs.
What is meant by dielectric constant?
Dielectric constant (ϵr) is defined as the ratio of the electric permeability of the material to the electric permeability of free space (i.e., vacuum) and its value can derived from a simplified capacitor model.
What is the Lorentz force equation?
Lorentz force, the force exerted on a charged particle q moving with velocity v through an electric field E and magnetic field B. Lorentz) and is given by F = qE + qv × B.
What is Langevin theory?
Langevin equation is a phenomenological stochastic differential equation of motion describing time evolution of a subset of the degrees of freedom for slowly relaxing (macroscopic) variables while the rapidly relaxing (microscopic) variables, which result in the stochastic nature in the equation.
What is Langevin theory of diamagnetism?
Langevin’s theory of Diamagnetism. Langevin gave a theory to explain the experimental results of curie . This concludes susceptibility of a diamagnetic material is independent of temperature and field strength . According to him an electron revolving in a circular orbit in. an atom is equivalent to a magnetic shell .
