Figure 19.16(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.

6 FAQs about [Electric field strength in capacitor plates]
How does the field strength of a capacitor affect rated voltage?
The electric field strength in a capacitor is directly proportional to the voltage applied and inversely proportional to the distance between the plates. This factor limits the maximum rated voltage of a capacitor, since the electric field strength must not exceed the breakdown field strength of the dielectric used in the capacitor.
Is field strength proportional to charge on a capacitor?
Since the electric field strength is proportional to the density of field lines, it is also proportional to the amount of charge on the capacitor. The field is proportional to the charge: E ∝ Q, (19.5.1) (19.5.1) E ∝ Q, where the symbol ∝ ∝ means “proportional to.”
