(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.
