While inductors store a current as a magnetic field, capacitors store voltage as an electrostatic field. Capacitors come in many sizes and shapes depending on the manufacturer and their intended use. A capacitor is constructed of two conductive surfaces separated by an insulator to store an electrostatic field between those surfaces.

B8: Capacitors, Dielectrics, and Energy in Capacitors
The presence of the insulating material makes for a weaker electric field (for the same charge on the capacitor), meaning a smaller potential difference, meaning a bigger charge-to-voltage ratio, meaning a bigger capacitance. How much bigger depends on how much the insulator is polarized which depends on what kind of material the insulator ...

By placing a parallel plate capacitor within a time-varying magnetic field, inductive voltage partially compensates the electrostatic voltage produced by the electric charges and accumulates a larger amount of charge on the plates.

It is worth noting that both capacitors and inductors store energy, in their electric and magnetic fields, respectively.

The switch is closed, and charge flows out of the capacitor and hence a current flows through the inductor. Thus while the electric field in the capacitor diminishes, the magnetic field in the inductor grows, and a back electromotive force (EMF) is induced in the inductor. Let (Q) be the charge in the capacitor at some time.
