Reading Feynman, there are various examples of finding voltages, forces, et cetera, when you know the charge involved. But going other way? Almost nothing. To be specific, how do you answer the following question [[NOT a homework question; self invented question]]:
A vacuum tube plate is connected to a 500 volt plate bias power supply. The plate is 1 sq cm [[1 cm high ; 1 cm circumference]], 5 mils thick. When there are no other influences on the plate, how many electrons , in Coulombs, are missing? IE, what is the charge?
