A 6.00-V battery is connected across the primary coil of a transformer having 50 turns. If the secondary coil of the transformer has 100 turns, what voltage appears across the secondary?
  1.24.0 V
  2.12.0 V
  3.6.00 V
  4.3.00 V
  5.none of those answers

Question 2

A circuit containing an AC generator, a capacitor, an inductor, and a resistor has a high-Q resonance at 1 000 Hz. From greatest to least, rank the following contributions to the impedance of the circuit at that frequency and at lower and higher frequencies. Note any cases of equality in your ranking.
   (a) XC at 500 Hz
   (b) XC at 1 500 Hz
   (c) XL at 500 Hz
   (d) XL at 1 500 Hz
   (e) R at 1 000 Hz


  1.(c) > (d) > (a) > (e) > (b)
  2.(a) > (d) > (b) > (c) > (e)
  3.(b) > (c) > (a) > (d) > (e)
  4.(d) > (a) > (e) > (c) > (b)
