Question 9
A capacitor with unknown capacitance is used for an experiment. Students connect the capacitor to a battery, allow the capacitor to become fully charged, and then isolate the capacitor. The students then insert dielectrics with different dielectric constants kappa , one at a time, between the plates of the capacitor and measure the potential difference V across the capacitor. Which of the following hypotheses can be tested with this data?
(A) For a given the potential difference V, the charge stored in a capacitor will increase as the dielectric constant of the material between the plates increases.
For a given the potential difference V, the energy stored in a capacitor will increase as the dielectric constant of the material between the plates increases.
For a given the potential difference V, the charge stored in a capacitor will increase as the capacitance of the capacitor increases.
(D) For a given stored charge, the breakdown voltage of a capacitor will decrease as the dielectric constant of the material between the plates increases.
(E) For a given stored charge, the potential difference across the plates of a capacitor will increase as the dielectric constant of the material between the plates increases.
