Homework Statement


Two capacitors C1= 6 μF and C2 = 12 μF are connected in series, and the resulting combination is connected to a 9.00 V battery. What is the potential difference across C2?


Homework Equations



V=Q/C

The Attempt at a Solution



Q isn't given so I'm not sure what I'm suppose to do here.

Since they are placed in series, what the equivalent capacitance of the system? Hence what is the total charge in the circuit?

Right so since, the charge on both capacitors is Q. What is the total capacitance of the series circuit C? When you get this value, what is the value of the total charge Q?
