# Dielectric permittivity of 1 and polarization

• eagleswings
In summary, in a spherical dielectric shell with a permittivity of 1, the charges will distribute themselves throughout the space as far from each other as possible due to the lack of polarization.

## Homework Statement

in a homework problem we have a spherical dielectric shell with permittivity of 1 [like a vacuum. inside are charges that are released and we have to say what the charge distribution will look like later. if the dielectric can be polarized, i know what the charges will do. but i think the permittivity of 1 means there is no polarization, and therefore the charges will distribute themselves throughout the space as far from each other as possible. is this correct?

## Homework Equations

no analytical solution required

## The Attempt at a Solution

no analytical solution required

, but yes, this is correct. The charges will distribute themselves throughout the space as far from each other as possible because there is no polarization of the dielectric with a permittivity of 1.

## 1. What is dielectric permittivity?

Dielectric permittivity is a measure of the ability of a material to store electrical energy in an electric field. It is also known as the electric constant or relative permittivity.

## 2. How is dielectric permittivity of a material determined?

The dielectric permittivity of a material is determined by measuring the capacitance of a parallel plate capacitor filled with the material and comparing it to the capacitance of a similar capacitor filled with air.

## 3. What is the significance of a dielectric permittivity of 1?

A dielectric permittivity of 1 indicates that the material has no ability to store electrical energy in an electric field. In other words, it is non-polar and does not experience any polarization when placed in an electric field.

## 4. How does polarization relate to dielectric permittivity?

Polarization is the process by which a material becomes electrically polarized when placed in an electric field. The degree of polarization is directly proportional to the dielectric permittivity of the material.

## 5. What factors can affect the dielectric permittivity of a material?

The dielectric permittivity of a material can be affected by factors such as temperature, pressure, and the frequency and strength of the electric field it is placed in. It can also vary depending on the crystal structure and chemical composition of the material.
