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 distances 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. While inserting the dielectric, the students inadvertently cause the distance between the plates of the capacitor to slightly increase. Which of the following values would have the least error introduced by the increased plate separation? A The charge stored on the plates 6 The potential difference between the capacitor plates when the dielectric is fully inserted с The energy stored in the capacitor when the dielectric is fully inserted D The capacitance of the capacitor when the dielectric is fully inserted E The answer cannot be determined without knowing the increase in plate separation.
