# Effect of dielectric on charges

• K Dhiraj Bhak
In summary, a dielectric is a material that can be polarized by an applied electric field, which can weaken the strength of the field and increase the capacitance of a capacitor. The dielectric constant measures a material's ability to be polarized and higher temperatures can affect the material's polarizability and insulating properties.

What happens To the force between 2 charges if a metal sheet or a dielectric sheet is kept in between the two charges ..(the charges are in vacuum)

What do you think will happen? Start by recalling that the vacuum is a dielectric.

## 1. What is a dielectric?

A dielectric is a material that can be polarized by an applied electric field. This means that the material's molecules will align themselves in a way that creates an internal electric field, which can affect the behavior of charges in the material.

## 2. How does a dielectric affect the strength of an electric field?

A dielectric can weaken the strength of an electric field by reducing the amount of force that the field exerts on charges in the material. This is due to the polarization of the material's molecules, which creates an opposing electric field that counteracts the applied field.

## 3. Can a dielectric increase the capacitance of a capacitor?

Yes, a dielectric can increase the capacitance of a capacitor by reducing the electric field between the plates, thus allowing for a greater amount of charge to be stored on the plates at a given voltage.

## 4. What is the relationship between dielectric constant and the effect of a dielectric on charges?

The dielectric constant is a measure of a material's ability to be polarized by an electric field. The higher the dielectric constant, the greater the effect of the dielectric on charges in the material.

## 5. How does temperature affect the effect of a dielectric on charges?

Temperature can affect the effect of a dielectric on charges in several ways. Higher temperatures can cause the material to become less polarizable, thus reducing the effect of the dielectric. Additionally, at high temperatures, some dielectric materials may break down and lose their insulating properties.
