8. A motors draws 2 A of current when running at full speed and connected to a 120 Volt line. Suppose the same motor is connected to a 220 Volt power source and as the result it runs 1.4 times faster than its full speed and draws 9 A. What is the armature resistance of the motor? A. 7.4 Ohms B. 8.4 Ohms C. 9.4 Ohms D. 10.4 Ohms E. 11.4 Ohms
