A planar capacitor consists of two metal plates of surface A = La.Lo (La, Lo: are respectively the width and the length of the two plates). Between these two plates of distance d there is a dielectric of permittivity ε = ε 0.ε r (with ε 0 = 8,854.10 −12 F/m the permittivity of the vacuum and ε r the variable relative permittivity) as shown in Fig. 1.
