A Y- connected, 10-KVA, 230- has a field winding resistance of 4.59. At an operation of 0.85 lagging power factor, the excitation current is recorded at 10A. the core loss is 300W, and the mechanical loss is 200W. If the corresponding efficiency is 84.9%. calculate the per- phase armature winding resistance.
