It is symbolized o. In general, permittivity is symbolized and is a constant of proportionality that exists between electric displacement and electric field intensity in a given medium.
WebThe permittivity is the multiplier that relates the Electric Flux Density and the Electric Field : In addition, it is known that the speed of light in free space is related to the permittivity and permeability of a medium: As you can see, the speed of light slows down in a dielectric relative to the speed in a vacuum.
