Capacitance is influenced by:

Capacitance is fundamentally related to how much charge a capacitor can store per unit voltage applied across its plates. The relationship between capacitance (C), charge (Q), and voltage (V) is expressed by the formula C = Q/V, indicating that as voltage increases, for a given amount of charge, the capacitance appears to influence how that charge is stored.

Higher voltage can affect the electric field strength between the plates of the capacitor, therefore indirectly impacting the capacitance in practical scenarios, especially in non-ideal conditions or when considering dielectric breakdown. However, capacitance itself is primarily determined by the physical characteristics of the capacitor: the surface area of the plates, the distance between them, and the properties of the insulating material (dielectric) between the plates.

In a more theoretical context, if voltage were to change, it could affect the effective operational conditions of the capacitor within a circuit, but the intrinsic capacitance value defined by the physical parameters remains constant.

This connection to voltage illustrates how an understanding of capacitance is essential for those working with electronics, as it directly affects circuit design, energy storage capabilities, and overall performance in AC and DC systems.
