BASIC AC ELECTRICAL GENERATORS - 5 - Rotating armature AC generators are typically used in applications involving small amounts of power. With larger amounts of power, a great deal more current flow occurs through the slip rings and brushes. It is difficult and expensive to build slip rings and brushes to carry large amounts of current.
