AC Generator & Transformer

A transformer has 120 turns in the primary coil and carries 5 A current. Input power is one kilowatt. To have 560 V output, the number of turns in secondary coil will be

Show answer and solution

Answer: (c)

Primary voltage: $V_p = \frac{P}{I_p} = \frac{1000}{5} = 200\text{ V}$
$\frac{N_s}{N_p} = \frac{V_s}{V_p} \Rightarrow N_s = 120 \times \frac{560}{200}$
$N_s = 336$
So the answer is (c) 336.
