(c.) Determine the core loss when the transformer is connected to a 4700 (primary) volt 60 cycle source and 4400 (primary) volt 50 cycle source. (d.) Calculate the efficiencies of the transformer for a power factor of 0.8 for 1/2 and 1 1/4 fractions of rated kilovolt ampere. (e.) Calculate the apparent power at which the transformer is at its maximum efficiency.
