For a given parallel plate capacitor disconnected from a battery after being charged, the potential difference across its plates depends on

Professor PC Thomas Classes · Answer

(a) : The potential difference across a capacitor is given by $V = \frac{Q}{C}$. Here, $Q$ is the stored charge on the plates, and $C$ is the capacitance. The capacitance $C$ inherently depends on the geometrical configuration of the capacitor (area of plates and distance between them) and the medium. Thus, $V$ depends on both the stored charge and the geometry.
