AC Generator & Transformer

The primary winding of a transformer has 500 turns whereas its secondary has 5000 turns. The primary is connected to an A.C. supply 20 V, 50 Hz. The secondary will have an output of

Show answer and solution

Answer: (c)

  1. VsVp=NsNp=5000500=10\dfrac{V_s}{V_p} = \dfrac{N_s}{N_p} = \dfrac{5000}{500} = 10
  2. Vs=10×20=200 VV_s = 10 \times 20 = 200\text{ V}
  3. A transformer does not change frequency, so it stays 50 Hz.
  4. So the answer is (c) 200 V, 50 Hz.
