Learn MoreTo begin with, you have a neutral plate. But as you start to charge it, the plate accumulates electrons. These accumulated electrons are extra for the plate and makes the plates, as a whole, charged. Thus when you try to put more charge on the plate, the existing charges of the plate repel any extra charges.
