Two parallel-plate capacitors with the same plate separation but different capacitance are connected in parallel to a battery.Both capacitors are filled with air.The quantity that is NOT the same for both capacitors when they are fully charged is:
A)potential difference
B)energy density
C)electric field between the plates
D)charge on the positive plate
E)dielectric constant

Question

Quizplus · Accepted Answer

When capacitors are connected in parallel, they have the same potential difference across them, but the charge on each capacitor depends on its capacitance. Therefore, the charge on the positive plate is not the same for both capacitors.
