2. The switch has been closed for a long period of time, and a constant current run
through the circuit. Assume that C,= 3.0 µF, C2 = 6.0 µF, R,= 4.0 kN, R2 = 7.0 kN. The
power dissipated in R2 is 2.40 W. (a) Find the charge in C1. (b) Now the switch is open.
After a long time, how much has the load changed in C2?
