Question

1. When a dielectric is inserted between the plates of a capacitor, the capacitance increases compared to the situation when vacuum is between the plates. Which choice best explains why this change happens?
   a. For a fixed voltage across the plates, less charge is on the plates compared to the vacuum situation.

   b. For a particular charge on the plates, the electric field between the plates is reduced compared to the vacuum situation.
   c. For a particular charge on the plates, the energy stored is increased compared to the vacuum situation.

   d. For a fixed voltage across the plates, the energy stored is decreased compared to the vacuum situation.
   e. For a fixed voltage across the plates, the electric field is increased compared to the vacuum situation.
