The Capacitance of a Parallel Plate Capacitor Changes When a Dielectric

question 42

Multiple Choice

The capacitance of a parallel plate capacitor changes when a dielectric is inserted between the plates. This is mainly due to

• A) the existence of denser matter than air or vacuum, which forms a barrier for electric field lines and reduces the electric field in the region.
• B) the polarizability of the material, which sets up an electric field opposite to the applied field, thus reducing the electric field strength in the region.
• C) the fact that dielectrics have excess charge that then "shields" the plates from each other, reducing the electric field in the region.
• D) None of these.
