Suppose one had two exposed parallhttp://www.bikeforums.net/images/editor/separator.gif
http://www.bikeforums.net/images/editor/separator.gifel plate capacitors. The spacing between + and - is 1.5mm. However, the two parallel plate capacitors are placed back to back, so the + of one capacitor only 1.5mm away from the + of the other.

My belief is that this is not an issue, that there should be no unwanted effects caused by their close proximity, because I see capacitors mushed together in circuits all the time. Will there be any sort of interaction between the two + charge plates?

What's wrong with your links?

Off hand I'd say the plates would tend to repel. Depending on how rigid and well anchored the plates were would determine how noticeable the effect is.

Are the plates open to the air, or covered by a dielectric? If they are insulated via a casing, close proximity shouldn't be an issue, but if the bare metal plates of each cap are touching another with no real insulation, that may cause capacitance or other effects in unexpected ways.

If the plates came from a mexican restaurant, be careful, they are hot.
