9. When two identical transformers are operating in parallel, they will share the load as under (1 Point) proportional to thier impedances inversely proportional to their impedances 50% 50%
11. a 240 V dc shunt motor has an armature resistance of 0.4 ohm and is running at the full load speed of 600 rpm with a full load current of 25 A. The field current is constant. also a resistance of 1 ohm is added in series with the armature, find the speed at full load. (1 Point) 535 rpm 717 rpm 443 rpm 258 222
