In the armature, an electromotive force is created by the relative motion of the armature and the field. When the machine is used as a motor, this EMF opposes the armature current, and the armature converts electrical power to mechanical power in the form of torque, and transfers it via the shaft. When the machine is used as a generator, the armature EMF drives the armature current, and the shaft's movement is converted to electrical power. In an induction generator, these distinctions are blurred, since the generated power is drawn from the stator, which would normally be considered the field.
A growler is used to check the armature for shorts, opens, and grounds.
Hence, the correct option is (A)
