A transformer has a primary windings of 800 turns and a secondary windings of 200 turns. When the load current on secondary is 80 A at 0.8 p.f, lagging, the primary current is 25 A at 0.707 p.f. lagging. Determine graphically or otherwise, the no-load current of the transformer and its phase with respect to the voltage.
