9. CHARGING A CAPACITOR At first, it is easy to store charge in the capacitor. As more charge is stored on the plates of the capacitor, it becomes increasingly difficult to place additional charge on the plates. Coulombic repulsion from the charge already on the plates creates an opposing force to limit the addition of more charge on the plates. Voltage across a …
