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)? 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. A 220V diesel-driven emergency generator is required to supply the following on full load: lighting load comprising one hundred, 100W and two hundred, 60W lamps, • Machinery loads of 25kw, • Navigational equipment loads which draw a current of 30A. (i) (ii) Calculate the maximum power demand. Assuming a generator efficiency of 85%, calculate the required power output of the diesel engine when the generator supplies all the loads at the same time (1 decimal place).
