Parallel Plate Capacitor
The capacitance of flat, parallel
metallic plates of area A and
separation d is given by the expression above where:
k = relative permittivity of the dielectric
material between the plates.
k=1 for free space, k>1 for all media, approximately =1 for air.
The Farad, F, is the SI unit for capacitance, and from the definition of capacitance is seen to be equal to a Coulomb/Volt.
