Two parallel-plate capacitors with different capacitance but the same plate separation are connected in series to a battery.Both capacitors are filled with air.The quantity that is the same for both capacitors when they are fully charged is:
A)potential difference
B)stored energy
C)energy density
D)electric field between the plates
E)charge on the positive plate

Question

Quizplus · Accepted Answer

When two capacitors are connected in series to a battery, the charge on the positive plate of both capacitors is the same. This is because the charge must be conserved and what flows into one capacitor must flow out and into the next in a series circuit.
