Re: Residual charge left on caps

When the shape of two conductors is different rectification may occur. A
sharp point tends to emit electrons and a half sphere tends to collect
electrons so a cup and point together forms a high voltage low current
rectifier. I use this method to rectify the output of a TC.     Robert   H
