The capacitance of a capacitor is Co. It is connected to a battery of voltage V which charges the capacitor. With the capacitor still connected to the battery, a slab of dielectric material is introduced between the plates of the capacitor.
Which of the following explains the effect of the dielectric slab in the above situation?
A. The electric field between the plates of the capacitor rises.
B. The potential difference between the plates falls.
C. The total charge on the capacitor increases.
D. The ability of the capacitor to store charge decreases.
