A current of 5 A is flowing at 220 V in a primary coil of a transformer. If the voltage produced in the secondary coil is 2200 V and 50 % of power is lost, then the current in the secondary coil will be

Options

  1. A2.5 A
  2. B5 A
  3. C0.25 A
  4. D0.025 A

Correct answer

C. 0.25 A

Step-by-step solution

The primary power is P_p = V_p I_p = 220 5 = 1100 W . With 50% power loss, the secondary power becomes P_s = 0.50 1100 = 550 W . Given the secondary voltage V_s = 2200 V , the secondary current is I_s = P_s V_s = 550 2200 = 1 4 = 0.25 A .
