Examine the figure shown. Note that C3 = 10.5 uF, and C1 = C2 = 2C3. Also the battery voltage is Vb = 39.0 volts.
What is the equivalent capacitance for this arrangement?
How much charge is stored on C1?
The Attempt at a Solution
C2 and C3 are in parallel, so I used C'=C2+C3
C' is in series with C1, so the total capacitance, C'' is:
which is equal to:
pluging in values, I get an answer of 12.6 uF. I am using an online homework program and am told that this is incorrect. What am I doing wrong?
For the second question, shouldn't I multiply my answer for the first part by the volts value given?
Thank you for you help.
