In figure, three capacitors C1,C2  and  C3 are joined to a battery. with symbols having their usual meaning, the correct conditions will be

At junction A, Q1 will be divided into Q2  and  Q3. Hence, Q1= Q2+Q3.  C2  and  C3are in parallel, so potential on them will be the same, i.e., V2=V3V will be divided into V1  and  V2(or  V3)Hence, V=V1+V2    or   V=V1+V3
