1. All capacitors are initially uncharged Switch 1 is first closed for several seconds, and then opened. Then switch 2 is
closed. Calculate the final potential differences V1, V2, and V3 across each capacitor, and indicate, on the diagram,
which plate is positive and which is negative for each capacitor. Take C1 = 6.0µF, C2 = 20.0µF, C3 = 30.0µF, and the
battery emf to be 9.0 volts.
