q a20-hp 250-vshuntmotor has a total armature -

Q. A20-hp, 250-Vshuntmotor has a total armature - circuit resistance of 0.25 and a field-circuit resistance of 200.At no load and rated voltage, the speed is 1200 r/min, and the line current is 4.5 A. At full load and rated voltage, the line current is 65 A. Assume the field flux to be reduced by 6% from its value at no load, due to the demagnetizing effect of armature reaction. Compute the full-load speed.
