c) A 230V D.C. shunt motor is now connected to the bus bars to drive a Freshwater pump. The motor has an input of 5kW when loaded. The armature and field resistances are 0.10 and 1000 respectively. Calculate the back e.m.f.value I (1 decimal place). (5 marks) d) A coil consumes 300W when connected into a 60V D.C. circuit. When connected to an A.C Circuit of 130v, it consumes 1200W. What is the coil's reactance. (1 significant figure)? [5 marks] e) A single-phase A.C motor has an input of 50.6A at 240V, the power input being 10kW and the output 9kW. Calculate the value of the apparent power (1 decimal place), power factor (2 decimal place) and the efficiency of the machine. [5 marks)
