Voltage regulator exams
An alternator is definitely an electrical generator that converts mechanical Vitality to electrical Strength in the shape of alternating current.[two] For good reasons of Price tag and simplicity, most alternators make use of a rotating magnetic discipline with a stationary armature.[three] Occasionally, a linear alternator or perhaps a rotating armature which has a stationary magnetic discipline is utilised. In basic principle, any AC electrical generator could be identified as an alternator, but commonly the phrase refers to modest rotating equipment driven by automotive and other interior combustion engines.
