  1. An electric generator converts mechanical energy to electrical energy by:
  2. A generator coil has 200 turns, area 0.050 m², and rotates at 60 Hz in a 0.40 T field. Calculate the peak EMF (in volts). (Use omega = 2pi f, pi approx 3.14)
  3. An ideal transformer with primary turns N_p and secondary turns N_s has voltage relationship:
  4. A transformer has 100 turns on the primary and 500 turns on the secondary. If the primary voltage is 120 V, calculate the secondary voltage (in volts).
  5. High-voltage power transmission is used because:
