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 primary voltage. if the resistance of the primary is 0.2 ohm and that of secondary is 2 ohm and the efficiency is 90%. calculate the heat losses in the primary and secondary coils
