I'm making a new stacked flat plate capacitor using sheets of aluminum foil
7.5"x9" trying to get 0.013 microfarads. Using the equation C=kA/d (k = 2
polyethyline) . I get 3.25 sq. meters, or 74 foil sheets, does this sound
right? My last capacitor had only 30 sheets. I'm using 6 layers of 5 micron
poly plastic between the sheets of aluminum.   Thanks, Phil B.
