Figure (PageIndex{5})(b) shows the electric field lines with a dielectric in place. Since the field lines end on charges in the dielectric, there are fewer of them going from one side of the capacitor to the other. So the electric field strength is less than if there were a vacuum between the plates, even though the same charge is on the plates.

About Photovoltaic Energy StorageThe Field Force and the Field Flux. Fields have two measures: a field force and a field flux.The field force is the amount of "push" that a field exerts over a certain distance. The field flux is the total quantity, or effect, of the field through space. Field force and flux are roughly analogous to voltage ("push") and current (flow) through a conductor, …

Placing a dielectric in a capacitor before charging it therefore allows more charge and potential energy to be stored in the capacitor.
