<p>(i) The primary of a transformer has 400 turns while the secondary has 2000 turns.If teh power output from the secondary at 1100 V is 12.1kW, calculate the primary voltage. (ii) If the resistance of the primary is 0.2<math xmlns="http://www.w3.org/1998/Math/MathML"><mi>&#937;</mi></math>&nbsp;and that of the secondary is 2.0&nbsp;<math xmlns="http://www.w3.org/1998/Math/MathML"><mi>&#937;</mi></math>&nbsp;and the efficiency of the transformer is 90%, calculate the heat losses in the primary and the secondary coils.</p>
