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

Though Candida and Aspergillus species are the most common fungal pathogens causing invasive fungal disease in the immunocompromised, infections due to previously uncommon hyaline and dematiaceous filamentous fungi are occurring more often today. Rare fungal infections, once accurately diagnosed, may require surgical debridement, immunotherapy, and newer antifungals used singly or in combination with older antifungals, on a case-by-case basis.

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
