All alternators Use a voltage regulator circuit which keeps the voltage at the ideal thirteen.8 to fourteen.two volts necessary to run the vehicle and charge the battery. Most newer cars Have a very voltage regulator that's Section of the alternator, but more mature autos hold the regulator for a individual aspect.

These were utilized for transmission of Morse code and, experimentally, for transmission of voice and songs.
