The potential diffrence across a series combination of 4(micro)F and 12(micro)F capacitor is 240V. What is the potential diffrence across 4(micro)F capacitor?

The same charge is on both capicator.
C=qV
q=C/V
so you have 4/V4 = 12/V12
and V4+V12=240
solve for them. I get V12 is 3 times V4, or V12=180, V4=60
check all that.
