• A capacitor is a device that stores electric charge and potential energy. The capacitance C of a capacitor is the ratio of the charge stored on the capacitor plates to the the potential difference between them: (parallel) This is equal to the amount of energy stored in the capacitor. The E surface. 0 is the electric field without dielectric.
Capacity, on the other hand, refers to the maximum amount of electrical charge that a component can hold. It is measured in coulombs and is a measure of the component's ability to store charge. In essence, capacitance is the inherent property of a component, while capacity is the practical limit of how much charge it can hold.
Capacitor and Capacitance are related to each other as capacitance is nothing but the ability to store the charge of the capacitor. Capacitors are essential components in electronic circuits that store electrical energy in the form of an electric charge.
If by "capacity" you mean the amount of net charge on the plates, then obviously that's not the same as the capacitance of the capacitor which is the charge divided by the voltage. The capacitance of a capacitor is greater if the work required per unit charge to separate the charge on the plates (i.e., the voltage) is less. Hope this helps.
Capacitance and capacity both have a relationship to voltage, but in slightly different ways. In the case of capacitance, the voltage across a capacitor is directly proportional to the charge stored on the capacitor. This relationship is described by the equation Q = CV, where Q is the charge, C is the capacitance, and V is the voltage.
The capacitance C of a capacitor is defined as the ratio of the maximum charge Q that can be stored in a capacitor to the applied voltage V across its plates. In other words, capacitance is the largest amount of charge per volt that can be stored on the device: C = Q V

Numerous research had been carried out to know about the relationship between specific capacitance and specific surface area of AC and a discrepancy between them was found. In spite of having a large specific surface area, relatively a small specific capacitance was obtained (<10 μF cm −2 ), much smaller than the theoretical EDL capacitance (15–25 μF …

Capacitance
Capacitance is the capacity of a material object or device to store electric charge. It is measured by the charge in response to a difference in electric potential, expressed as the ratio of those quantities. Commonly recognized are two closely related notions of capacitance: self capacitance and mutual capacitance.

Converting Capacitance to Impedance
A capacitor''s capacitance is directly proportional to the surface area of its plates and inversely proportional to the separation between these plates. However, net capacitance also depends on the dielectric constant of the substance separating the plates. When converting the impedance of a capacitor, we use the formula Z = -jX. Keep in mind ...

fig.4 = with minimum distance between the plates, the max attraction between them enables both to hold max amount of charges. As Capacitance C = q/V, C varies with q if V remains the same (connected to a fixed potential elec source). So, with decreased distance q increases, and so C increases.
