Cách sử dụng
A commutator is a part of an electrical device that helps change the direction of electrical current. It's found in motors, generators, and other electrical equipment. It's made up of segments of copper or other metals that are insulated from each other and attached to the ends of the wires that carry the current. When the commutator rotates, it switches the direction of the current in the wires, which makes the device work. If you're studying electronics or electrical engineering, you'll likely encounter this term frequently.
