A 208 V Y-connected synchronous motor is drawing 40 A at unity power factor from a 208 V power system. The field current flowing under these conditions is 2.7 A. Its synchronous reactance is 0.8 Ω. Assume a linear open-circuit characteristic.
The filed current (in A) required to make the motor operate at 0.8 power factor leading isEnter numerical value using the virtual keypad. Round off where necessary.
