Commutators are mechanical or electronic devices that facilitate the flow of current in electrical circuits. Some synonyms for the word "commutators" include "switches," "converters," "inverters," "transformers," "alternators," "rectifiers," and "generators." Each of these terms is specific to a particular type of mechanism or device that serves a similar purpose to the commutator. For example, a rectifier is a type of commutator that converts alternating current (AC) to direct current (DC), whereas an inverter is a type of commutator that converts DC to AC. No matter what term is used, commutators and their synonyms play a crucial role in various technical and engineering applications.
