The amount of charge (Q) a capacitor can store depends on two major factors—the voltage applied and the capacitor''s physical characteristics, such as its size. A system composed of two identical, parallel conducting plates separated by a distance, as in Figure (PageIndex{2}), is called a parallel plate capacitor .
Our capacitor has two dielectrics in series, the first one of thickness (d_1) and permittivity (epsilon_1) and the second one of thickness (d_2) and permittivity (epsilon_2). As always, the thicknesses of the dielectrics are supposed to be small so that the fields within them are uniform.
