A capacitor with plates of known area and known plate separation is used for an experiment. Students connect the capacitor to a battery and allow it to become fully charged. The students then isolate the capacitor from the battery and slowly insert a material with dielectric constants K into the capacitor. While the dielectric is being inserted, the students measure the distance x that the material has been inserted into the capacitor and the potential difference V across the capacitor plates while keeping the spacing between the capacitor plates constant. The students collect data until the dielectric completely fills the space between the capacitor plates.
a. Which of the following graphs best predicts how the potential difference △V across the capacitor plates will change as the distance x that the dielectric is inserted between the plates increases?
b. A dielectric is inserted between the plates of an isolated, charged capacitor. As the dielectric is being inserted, will the electric field between the plates and the electric potential difference across the plates of the capacitor increase, decrease, or remain the same?
