bizarre capacitance

Hi There are actually two factors. Dielectric absorption is one of them. The other is induced charge. Others have described dielectric absorption. Induced charge works like this. When the internal part is discharged, it induces a charge on all the dust and surfaces that are not covered with conductive paint. These get a negative charge on them from doing this discharge. Over time, this outside charge leaks to the conductive surfaces, reinducing a positive back onto the internal surface. The two are factors. I've found that the induced charge is a major factor. While holding the short, wiping all the external surfaces reduces the charge that builds by quite a bit.
