A Parallel-Plate Capacitor Consists of a Set of Two Parallel

question 49

Multiple Choice

A parallel-plate capacitor consists of a set of two parallel plates of area A separated by a distance d.This capacitor is connected to a battery that maintains a constant potential difference across the plates.A slab of a dielectric material is inserted in the region between the plates and completely fills it.What changes would you observe as the dielectric is inserted? (There could be more than one correct choice. )

• A)Only the charge on the plates of the capacitor would change.
• B)Only the capacitance would change.
• C)Both the charge on the plates of the capacitor and its capacitance would change.
• D)The potential difference across the plates would increase.
• E)Nothing would change.
