Homework Statement
Switch S has been closed for a long time, and the electric circuit shown in the figure below carries a constant current. Take C1 = 3.00 µF, C2 = 6.00 µF, R1 = 4.00 k, and R2 = 7.00 k. The power delivered to R2 is 2.60 W.
Homework Equations
(a) Find the charge on C1.
(b) Now the switch is opened. After many milliseconds, by how much has the charge on C2 changed?
The Attempt at a Solution
I said power = I[tex]^{2}[/tex] * R
then 2.6 = I[tex]^{2}[/tex] * R then I got the current I and it was 0.0193
Then I got V1 = I R[tex]_{1}[/tex]
I added V1 + V2 to get the V for the battery
then to get charge on C1 is the maximum charge because the switch has been opened for a long time then
Q = C1 * V
but I got error :S :S
