Question

A uniformly polarized dielectric amounts to induced ______ charge density but no ______charge density.

• A. surface
• B. volume

Answer 1

Uniform polarization:

1. When the charge density is throughout the volume of a body, then the charge per unit volume is called volume charge density.
2. The volume charge density is equivalent to zero if the material is uniformly polarized.
3. All dipoles are completely aligned in an evenly polarized material of thickness and polarization.
4. The alignment of such numerous dipoles results in a positive surface charge solely on a single side of the material and a negative surface charge on the other.
5. A dielectric that is evenly polarized has induced surface charge density but no volumetric charge density.
6. Charge given in the dielectric always resides on its surface, so charge inside the dielectric will be zero.
7. Hence, volume charge density becomes zero but surface charge density is not zero.

Therefore, a uniformly polarized dielectric amounts to induced surface charge density but no volume charge density.
