explain the function of the brush ring in electric generator
Brush (electric) A brush is a device which conducts current between stationary wires and moving parts, most commonly in a rotating shaft. Typical applications include electric motors, alternators and electric generators.
Electric guitar An electric guitar is a guitar that uses one or more pickups to convert the vibration of its strings into electrical signals. The vibration occurs when a guitarist strums, plucks, fingerpicks, or taps the strings. The pickup used to sense the vibration generally uses electromagnetic induction to do so, though other technologies exist. In any case, the signal generated by an electric guitar is too weak to drive a loudspeaker, so it is sent to a guitar amplifier before being sent to the speaker, which converts it into audible sound.
