electric potential and fields--capacitors
What is the potential difference across each capacitor in the figure?
What is the potential difference across each capacitor in the figure?
Q=C/V
Parallel capacitors: add up
series capacitors: (1/c + 1/c...)^-1

I tried using Q=C/V and got 45,36,54 microC. And I tried what they have on the site above (although it didn't really make a whole lot of sense as to why they were doing what they did). I understand the concept of how to add capacitors, but how to get their individual charges...? I also tried dividing the voltage by 3 because there are three capacitors...Thanks!
