Question

Three identical capacitors each of capacitance c are connected in series with a battery of emf v and get fully charged now the battery is removed

Answer 1

Answer:

When capacitors are in series ,in this case capacitance of all are same and charge on all the capacitors are also same. Hence voltage will also be same

V=3V′

V′=3V

Now if we connect them in parallel, all are at common potential difference V/3.
