Problem 8.4 and 8.5

Use the machine parameters in Problem 8.4 to perform the necessary calculations to draw the steady-state voltage-current phasor diagram when the machine is operating at rated terminal voltage (Et = 1 pu) and rated terminal current (It = 1 pu) at 0.9 leading power factor. Assume no saturation.
