**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:
