The electric displacement field is defined as:
$ oldsymbol{D} = varepsilon_0 oldsymbol{E} + oldsymbol{P} =varepsilon oldsymbol{E}$.

where:
  ?0 is the permittivity of free space
  E is the electric field intensity
  P is the polarization of the medium

The folliwing use RC-circuit to show relation between displacement current and electric field.

To make it easier, the value of ?0 is assigned as 0.5

Un-check the off check box to connect the DC voltage source to the RC circuit (ON).
 k is the dielectric constant $varepsilon/varepsilon_0$.
You can adjust voltage source Vs, resistance R, capacitance C.
