Capacitor capacitance calculation rules
Notice from this equation that capacitance is a function only of the geometry and what material fills the space between the plates (in this case, vacuum) of this capacitor. In fact, this is true not only for a parallel-plate capacitor, but for all capacitors: The capacitance is independent of Q or V.If the charge changes, the potential changes correspondingly so that Q/V remains constant.
