suppose a battery connected to a capacitor only (and no dielectric inserted), the potential difference of the capacitor will increase till it becomes equal to that of the battery, suppose we put dielectric in the capacitor, this will decrease potential difference of the capacitor, now the capacitor would have less potential difference than the battery, what will happen next, will the potential difference of the capacitor increase again till it becomes equal to that of the battery again, if it will not increase where will the rest of voltage supplied by the battery go, and if it will increase then the voltage and Q are the same as without dielectric so the capacitance will be the same as without dielectric while this is not true as permittivity increased, or will the potential difference increase again and the Q increase and the idea of Q being constant before/after inserting dielectric is while we aren't connecting a battery only
