Great explaination of what causes one material to have a dielectric constant
of 2.3 (like PE ) and another to have a value of 6,000 (like barium titanate).
I have heard that some "super capacitors" have porous metallic plates to
increase the surface area and thus the capacitance............any ideas on
this Bert ?
