Problem 3.1 Two capacitors, C1 and C2, are connected in series. Capacitor C1 has a value of 1uF, the value of C2 is unknown. The series connection of capacitors is charged from a 12V battery. Capacitor C1 gets charged to 8V and C2 gets charged to 4V. What is the capacitance of C2? Assume that the capacitors are uncharged initially.

Problem 3.2 Practice with complex numbers. Compute the following complex quantities:
