Learn MoreAnywhere in that electric field we have a field strength is measured in how many Newtons of force a Coulomb of charge feels: N/C. As we saw earlier there is very little force between just two charged particles, but a Coulomb of charge (about 6.241509×10 18) changes the game entirely!. The force (F) felt by a charged particle in an electric field is calculated using:

Learn MoreThe electric field, however, is now only (E = V/d_2) and (D = epsilon_0 V/d_2). But Gauss''s law still dictates that (D = sigma), and therefore the charge density, and the total charge on the plates, is less than it was before. It has gone into the battery. In other words, in doing work by separating the plates we have recharged the ...
