1975E2. In the diagram above, V=100 volts; C1=12 microfarads; C2=24 microfarads; R=10 ohms. Initially, C1 and C2 are uncharged, and all switches are open.
a. First, switch S1 is closed. Determine the charge on C1 when equilibrium is reached.
b. Next S1 is opened and afterward S2 is closed. Determine the charge on C1 when equilibrium is again reached.
c. For the equilibrium condition of part (b), determine the voltage across C1.
d. S2 remains closed, and now S1 is also closed. How much additional charge flows from the battery?
