Suppose I want to collect 1 esu (2.081 billion charges) on a plate or on a ball, what is the smallest radius that will carry such a charge?
From data I gathered around a ball of 1 mm of radius would be large enough, can you confirm that? What material is best, steel, silver or non-conductive material?
Also, can I measure the charge on the plate/ball with an accuracy of five figures with a cheap instrument (less than 50-100 $) ?
Thanks
