The reason the capacitance of a parallel plate capacitor having a dielectric between the plates changes is due to

Question

Quizplus · Accepted Answer

Dielectric materials have the property of polarizability. When an electric field is applied to a dielectric, the molecules in the material shift slightly, creating their own electric field that opposes the applied field. This reduces the overall electric field between the plates, and thus the capacitance of the capacitor increases. Options A and C are incorrect, as they do not accurately describe the behavior of dielectric materials in a capacitor. Option D is incorrect, as there is a clear explanation for why capacitance changes in the presence of a dielectric material.
