31. The primary of a transformer has 200
turns and the secondary has 1000 turns.
If the power output from the transformer
at 1000 V is 9 kW, calculate
(i) The primary voltage and
(ii) The heat loss in the primary coil if
the resistance of the primary is 0.222
and efficiency of the transformer is
90%.

Answer:
The overall efficiency of a transformer is 90%. the transformation is rated for an output of 9000 watt. the primary voltage is 1000 volt. the ratio of turn in the primary to the secondary coil is 5:1 the iron losses at full load are 700 watt, the primary coil has a resistance of 1 ohm in the above the current in the primary coil is
