I'm stuck on this physics problem...
![Image]()
for my problem, Vab=26V, c1=2.8uF, c2=5.45uF, c3=5.85uF, I need to find the charge on each capacitor...
In a different problem they have c1=3.0uF, c2=5.0uF, c3=6uF, Vab=120V
..the have the charge on c1=150uC. i can't figure out how they got it.
In a similar example it was solved by adding all the capacitors, and using that total capacitance [times] voltage to get total charge. then each individual capacitor [divided] by total capacitance [times] total charge equaled the charge on each capacitor.....sorry if that doesn't make any sense.
c1+c2=c'
c' x V = Qtotal
[c1/c'] x Qtotal = q1 (charge on c1)
then
[c2/c'] x Qtotal = q2 (charge on c2)
can anyone help?
thanks,
Rosie
