AC Generator & Transformer

A transformer having an efficiency 80% is working on 200200 V and 44 kW power supply. If the current in the secondary coil is 55 A, the voltage across the secondary coil and the current in the primary coil, respectively, are

Show answer and solution

Answer: (b)

  1. Ip=PinVp=4000200=20 AI_p = \dfrac{P_{in}}{V_p} = \dfrac{4000}{200} = 20\text{ A}
  2. Pout=0.8×4000=3200 WP_{out} = 0.8 \times 4000 = 3200\text{ W}
  3. Vs=32005=640 VV_s = \dfrac{3200}{5} = 640\text{ V}
  4. So the answer is (b) 20 A, 640 V.
