Potential difference across capacitors

[Krushnaraj Pandya]

Homework Statement

The figure shows part of a complete circuit. The potential at point A is greater than that of B by 19 volts what is the potential difference in volts across the three microfarad capacitor?

Homework Equations

All relevant to electric circuits

The Attempt at a Solution

From Kirchhoff's law, net potential difference across a closed loop should be 0. V(a)-(b)=19 V. Therefore, the net potential difference across given figure should be -19 V. I'm having trouble with the sign conventions related to this, since I don't know what sign to put with the batteries, otherwise since all capacitors are in series- charge across them is the same. I'd appreciate some insight.

The figure shows part of a complete circuit.

Which figure?

The voltage would not be equivalent across capacitors in series. The voltage across all of the capacitors is the sum of the voltage across each individual one.
