A transformer on no-load has a core-loss of 50 W, draws a current of 2 A and has an induced EMF of 230 V. Determine the no-load power factor and core-loss current.

Power factor = 0.108 lagging, core-loss current = 2 sin(cos-1 0.108) A

Power factor = 0.208 lagging, core-loss current = 0.416 A

Power factor = 0.108 lagging, core-loss current = 0.216 A

Power factor = 0.208 lagging, core-loss current = 2 sin(cos-1 0.208) A
