The primary of a transformer has 200 turns and secondary has 1000 turns. The power output from secondary at 1000 V is 9 kW. Calculate primary voltage and heat loss in primary. Take resistance of primary coil `0.2 Omega` and efficiency of transformer = 90%.

(i) The primary of a transformer has 400 turns while the secondary has 2000 turns. If the power output from the secondary at 1100 V is 12.1 kW, calculate the primary voltage. (ii) If the resistance of the primary is 0.2 Omega and that of the secondary is 2.0 Omega and the efficiency of the transformer is 90 % , calculate the heat losses in the primary and the secondary coils.
