## Main Question or Discussion Point

Hi,

Suppose we apply an electric field

I know that the field

1. what is the physical meaning behind [tex]\epsilon_{0}[/tex]

2. Specifically, why is the contribution of our applied field

Thanks in advance.

Suppose we apply an electric field

**E**to a dielectric material. It is my understanding that the actual field that is formed as a result of our applied field is given by the displacement field**D**.**D**=[tex]\epsilon_{0}[/tex]**E+P**I know that the field

**P**is due to the polarization of the atoms withing the dielectric.1. what is the physical meaning behind [tex]\epsilon_{0}[/tex]

**E**?2. Specifically, why is the contribution of our applied field

**E**being scaled by the permittivity of free space [tex]\epsilon_{0}[/tex]?Thanks in advance.
