The startup current for large induction motors is very high because
 
  A) the power factor is low B) the counter emf is very high
  C) the starting impedance is slightly capacitive D) the starting impedance is purely inductive

Question 2

After troubleshooting a series RL circuit, you check the resistance of the inductor and it is around 40 ohms. What conclusion does this bring you to?
 
  A) Since the inductor's voltage was nearly zero, the inductor is probably okay, so the resistor must be open.
  B) Since the inductor's voltage was nearly zero, the inductor is probably okay so the resistor must be shorted.
  C) Since the inductor's voltage was nearly zero, you are sure the windings have shorted.
  D) not enough information
