text: Essentially, a capacitor is like a small battery, producing a potential difference (i.e., a voltage) between the two plates, separated by the insulating divider called the dielectric (which can be many materials, but is often ceramic, glass, wax paper or mica), which prevents current from flowing from one plate to the other, thereby maintaining the stored charge.
