A motor is designed to operate on 117 V and draws a current of 12.2 A when it first starts up. At its normal operating speed, the motor draws a current of 2.30 A. Obtain (a) the resistance of the armature coil,(b) the back emf developed at normal speed, and (c) the current drawn by the motor at one-third of the normal speed.
