Capacitance of an isolated parallel plate capacitor does not depend upon

The capacitance of an isolated parallel plate capacitor does not depend on:

1. The charge stored in the capacitor: Capacitance is a measure of a capacitor's ability to store charge. It is defined as the ratio of the charge Q on each conductor to the potential difference V between them. The charge stored in the capacitor can change with the applied voltage, but the capacitance remains constant because it is a property of the physical structure of the capacitor (the area of the plates and the distance between them).

2. The potential difference between the plates: While the potential difference can affect the amount of charge stored in the capacitor, it does not change the capacitance. The capacitance is determined by the physical characteristics of the capacitor itself.

3. The material between the plates (as long as it is a non-conductive material): The capacitance of a parallel plate capacitor is directly proportional to the permittivity of the material between the plates. However, if the material is non-conductive (an insulator), the capacitance does not depend on the specific material.

In summary, the capacitance of an isolated parallel plate capacitor depends only on the physical characteristics of the capacitor (the area of the plates and the distance between them), and not on the charge, potential difference, or specific non-conductive material between the plates.
