Question

A 1 − Ω transformer with turns-ratio of 150/450 and operates at a maximum flux of 7.5 mW b at 50 Hz. Working on no load takes 0.24 kV A at a power factor of 0.26 lagging from the supply. If it supplies a load of 1.2 kV A at a power factor of 0.8 lagging, determine (a) the magnetizing current, (b) the primary current, and (c) the primary power factor.
