I agree. >In other >words, this ion current from the air would be a leakage path for the >electret and not a benefactor. It would only be a leakage current, if charge could actually reach the electret. However, if the electret is well insulated, then all you get is a charge build up. Essentially, you end up with a capacitor within a capacitor. However, whether or not one can be discharged with discharging the other, I don't know. IOW can one discharge the accessible capacitor with "discharging" the electret? [snip] Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
