Unformatted text preview: the negative plate if we know the total charge q on the plate. Then, the number of electrons n = q / e , where e is the electron charge in coulomb. Second idea: The charge q of the plate is related to the voltage V to which the capacitor is charged: q = CV . Thursday, September 16, 2010...
