The electric field of the capacitor remains unchanged when it is charged

The empty capacitor will tend to suck the material in, just as the charged rod in Chapter 1 attracted an uncharged pith ball. Now let us suppose that the plates are connected to a battery. (Figure (V.)21) (text{FIGURE V.21}) This time the potential difference remains constant, and therefore so does the (E)-field, which is just (V/d).
