A voltage V is applied to the primary coil of a step-up transformer with a 3:1 ratio of turns between its primary and secondary coils. A resistor R connected to the secondary dissipates a power P = 100 W.
 
  How much power is dissipated by the same resistor when the ratio of turns in the transformer is changed to 24:1 and the same input voltage is used?
  A) 12,000 W
  B) 2400 W
  C) 24,000 W
  D) 6400 W
  E) 100 W

Question 2
