N S Capacitor A capacitor is most simply defined as two conductors separated by a dielectric . It is easier to grasp the significance of this definition by looking at a commonly used model for a capacitor that is shown here. A capacitor is also called a condenser . N Charged Capacitor A capacitor is said to be charged when there are more electrons on one conductor plate than on the other. The plate with the larger number of electrons has the negative polarity .
