Question

If a linear isotropic dielectric is placed in an electric field of strength E, then the polarization P is (A) independent of E (B) inversely proportional to E (C) directly proportional to √E (D) inversely proportional to √E

Tardigrade Admin · Accepted Answer

For linear isotropic dielectric, Polarization P = xe E where xe is a constant characteristic of the dielectric and is known as the electric susceptibility of the dielectric medium.

Q. If a linear isotropic dielectric is placed in an electric field of strength E, then the polarization P is

independent of E

inversely proportional to E

directly proportional to $E$

inversely proportional to $E$

directly proportional to E

For linear isotropic dielectric,
Polarization $P = x_{e} E$
where $x_{e}$ is a constant characteristic of the dielectric and is known as the electric susceptibility of the dielectric medium.
