Why is capacitance inversely proportional to voltage? And not …

I understand that the capacitance should be inversely proportional to the electric field, since if the electric field is greater, the charges can leak out towards the other plate. But why should ... $begingroup$ @Steeven I''m referring to the phenomenon where if, say, some negative charge appears on one plate, an equal amount of positive charge …

8.4: Energy Stored in a Capacitor

The energy (U_C) stored in a capacitor is electrostatic potential energy and is thus related to the charge Q and voltage V between the capacitor plates. A charged capacitor stores energy in the electrical field between its plates. As the capacitor is being
