A transformer has 120 turns in the primary coil and carries 5A current. Input power is one kilowatt. To have 560 V output, the number of turns in secondary coil will be

Options

  1. A168
  2. B200
  3. C336
  4. D400

Correct answer

C. 336

Step-by-step solution

Input power is given by P_ in = V_p I_p 1000 = V_p 5 V_p = 200 V Using the transformer ratio formula: V_s V_p = N_s N_p 560 200 = N_s 120 N_s = 560 120 200 N_s = 336 Answer: 336
