(a) If the load is increased until the armature current has risen to 60 amp, what will be the new value of speed ? (b) If the load is reduced until the armature current has dropped to 25 amp, what will the speed become ? (ii) (a) If an attempt is made to start the motor of part (i) without auxiliary resistance, what will be the value of the current at the instant of closing the switch ? (b) What series resistance should be inserted in order that the armature current at the moment of starting may be limited to 1.5 times the normal value of 50 amp ?\",\"src\":\"stemez-ElectricalMachines\"}","display_format":"text","language":"","answer_status":"published","assets":[],"source_url":"https://huggingface.co/datasets/TIGER-Lab/MMLU-Pro","history":"initial import","indexing_mode":"index","subproblems":[],"grids":[]}
