A series ac circuit has a resistance of 2.0 k, a capacitance of 8.0 F, and an inductance of 9.0 H. If the frequency of the alternating current is 4.0/ kHz, by what angle does the voltage lead the current?
 
  A) -3.1 rad B) +36 rad C) +1.5 rad D) +3.1 rad E) -1.8 rad

Question 2

Consider two copper wires of equal cross-sectional area. One wire has 3 times the length of the other. How do the resistivities of these two wires compare?
 
  A) The longer wire has 9 times times the resistivity of the shorter wire.
  B) The longer wire has 27 times times the resistivity of the shorter wire.
  C) The longer wire has 3 times the resistivity of the shorter wire.
  D) Both wires have the same resistivity.
