Different Capacitors in a Circuit

[member 217843]

Homework Statement

Which of the following capacitors (A vs. A2, which are identical) will have a larger charge, charge accumulation, voltage, energy stored? (Assume that the only difference between the two circuits is the size of the other capacitor in the circuit, as shown.)

Homework Equations

Q=VC, U=1/2CV^2
Net change in voltage in any closed loop in a circut must be 0.

The Attempt at a Solution

Originally, I thought that the voltage of both A and A2 would be the same, because there are two capacitors in a series in each circuit. But I think this is wrong because it makes the charge, charge accumulation, and energy stored all 'same' as well.

When a capacitor is charged, it gets +Q on one plate and -Q on the other. Equal charge on each side. Also, in your series circuit, the total charge in the middle (right plate of one capacitor and left plate of the other) must be zero (because there is no conductor going from there to the battery to pass a charge). That should be enough info for you!
