Introducing a dielectric into a capacitor decreases the electric field, which decreases the voltage, which increases the capacitance. A capacitor with a dielectric stores the same charge as one without a dielectric, but at a lower voltage. Therefore a capacitor with a dielectric in it is more effective. The field produce due to the polarization of material minimize the effect of external field. Hence, the electric field inside a dielectric decreases when it is placed in an external electric field.
