AC Generator & Transformer

A step-up transformer has 300 turns of primary winding and 450 turns of secondary winding. A primary is connected to 150 V and the current flowing through it is 9A. The current and voltage in the secondary are

Show answer and solution

Answer: (d)

  1. Vs=VpNsNp=150×450300=225 VV_s = V_p\frac{N_s}{N_p} = 150 \times \frac{450}{300} = 225\text{ V}
  2. Is=IpNpNs=9×300450=6 AI_s = I_p\frac{N_p}{N_s} = 9 \times \frac{300}{450} = 6\text{ A}
  3. So the answer is (d) 6.0 A, 225 V6.0\text{ A},\ 225\text{ V}.
