A 5-HP 230-V shunt motor takes 18A when operating at full load. The shunt field resistance is 115Ω and the armature resistance is 0.25Ω. Assume a 3-V brush drop. (a) Calculate the value of the starter resistor if the armature current is limited to 1.5 times the rated value at the starting instant. (b) Calculate the resistance which is cut out of the starter in moving to the second stud, assuming that this is done when the counter EMF is 74V and that the armature current immediately jumps to a
