The strength of an electric field (E) is proportional to the applied potential difference (V) and inversely proportional to the distance (d) between two charged plates. The electric field strength is thus given by:
E = V / d
where E is the electric field strength (in V/m), V is the applied potential difference (in V), and d is the distance separating the plates (in m).
The electric flux density (D) is given by the ratio of charge (Q) to area (A). Thus:
D = Q/A
where D is the electric flux density (in Coulomb/m2), Q is the charge (in Coulomb), and A is the area (in m2).
