Potential difference across capacitors

[QUOTE="Krushnaraj Pandya, post: 6039486, member: 646372"] [h2]Homework Statement [/h2] 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? [h2]Homework Equations[/h2] All relevant to electric circuits [h2]The Attempt at a Solution[/h2] 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. [/QUOTE]
