Electrical permittivity...in mathematical terms, i.e I need the derivation...WITHOUT using 'curls'.
Didn't find it online.

The permittivity of a medium is a constant that is connected to the electrical properties of that medium.Amongst other places it appears in Coulombs law and along with permittivity**( a magnetic constant ) the formula for the speed of light.
In mks units, the capacitance of a rectangular capacitor of relative permittivity e, separation d, and area A is
C = e e_{0} A/d Farads
where e is relative permittivity (unitless)
e_{0} is the permittivity of free space, 8.85 x 10^{-12} Farads per meter.
**The magnetic constant is permeability.
