capacitor circuit question urgent!!

URGENT! question regarding capacitors. posted this in another thread but felt the need to start another thread as i'm not sure how many people are checking that.

Say you have a series circuit with three capacitors and a 12V supply. What is the voltage across each capacitor? Does capacitance affect this voltage?

And what happens when the capacitors are in parallel? how is the voltage distributed throughout the circuit?
thanks!

In series each capacitor would have different voltages across them but current the same, therefore Q=CV mainly depends on voltage (and capacitance of course).
In parallel each capacitor would have the same voltage across them but current changes, therefore Q=CV depends mainly on charge (and capacitance of course).

Someone please confirm.
In parallel, the voltage across each capacitor is the same. In series, the charge on each capacitor is the same.

If you have a series circuit with three capacitors and a 12V supply.
The voltage across each capacitor would be 4V. :smile:
... provided they are of the same capacitance.
