What happens to the charges within a dielectric material when it is placed in an external electric field?

When a dielectric material is placed in an external electric field, how do the positive charges within the dielectric move?

What is the primary effect of the alignment of electric dipoles within a dielectric material when placed in an external electric field?

A dielectric material consists of both polar and nonpolar molecules. Which mechanism contributes to its polarization when placed in an external electric field?

What does the dielectric constant ($\kappa$) represent?

A material has a permittivity of $\varepsilon = 8.85 \times 10^{-11} \frac{C^2}{N \cdot m^2}$. Given that the permittivity of free space is $\varepsilon_0 = 8.85 \times 10^{-12} \frac{C^2}{N \cdot m^2}$, what is the dielectric constant ($\kappa$) of the material?

Three different materials are being considered for use as the dielectric in a capacitor. Material A has a dielectric constant of 2, Material B has a dielectric constant of 5, and Material C has a dielectric constant of 7. Which material will result in the highest capacitance for the capacitor, assuming all other factor...

What is the direction of the induced electric field inside a dielectric material when it is placed in an external electric field?

How does the induced electric field within a dielectric affect the total electric field strength inside the dielectric?

A parallel-plate capacitor has an external electric field of $E_0$. When a dielectric is inserted, an induced electric field $E_i$ is created such that the net electric field is reduced. If $E_0 = 1000 \frac{V}{m}$ and the dielectric constant $\kappa = 5$, what is the net electric field $E$ inside the dielectric?
