C' = eps * k * x * k * y / (k * z) = k * eps * x * y / z = k * C
so you see that capacitance scales of the same factor
Hope this clarifies Enrico

Posted - Feb 23 2008 : 09:42:19 Thanks for your reply! I am surprised about your answer about capacitance scaling in 3D.
If I use the equation of a simple parallel plate capacitor C =eps*A/d
If I scale all 3 dimension x,y,z by a constant factor then C should go up since the area goes up as d2?
Thanks for clarifying this!
