An ideal transformer converts 220 V a.c. to 3.3 KV a.c. to transmit a power of 4.4 KW. If primary coil has 600 turns then alternating current in the secondary coil is

Options

  1. A4 3 A
  2. B3 4 A
  3. C1 3 A
  4. D2 3 A

Correct answer

A. 4 3 A

Step-by-step solution

For an ideal transformer, the input power is equal to the output power. P_ out = P_ in = 4.4 kW = 4400 W The output power is given by P_ out = V_s I_s 4400 = 3300 I_s I_s = 4400 3300 = 4 3 A Answer: 4 3 A
