A)potential difference
B)energy density
C)electric field between the plates
D)charge on the positive plate
E)plate separation

Question

Quizplus · Accepted Answer

In a parallel-plate capacitor, the potential difference (or voltage) across the plates is the same for both capacitors, regardless of their capacitance. This is because they are connected in parallel to the same battery, which maintains a constant potential difference. The energy density, electric field between the plates, charge on the positive plate, and plate separation will all differ between the two capacitors due to their different capacitances. Therefore, the only quantity that remains the same is the potential difference.
