If a capacitor is connected to a battery, and allowed enough time to charge, the battery will maintain a constant voltage drop across the capacitor. This means that ∆V cannot change. It turns out that the effect on the capacitor due to inserting a dielectric is still the same; the capacitance increases by a factor of k.
