An alternator is considered as one of the main components of the car’s charging system. Not only is it responsible for charging the battery when the car is on, it is also responsible for powering all the car’s electrical components.

The alternator is secured to the engine using a tube, and it runs using a drive belt. Immediately when the engine starts turning, the shaft also starts spinning. The spinning is what makes production of electricity possible. The electricity produced by the alternator is called Alternating Current, commonly referred to as AC. This current needs to be changed into a different type of current that the car’s electric system works with, which is called Direct Current, or in short, DC. For the conversion to occur, the alternator employs a small device attached to it called a rectifier to convert AC to DC.

The final voltage that is outputted by the alternator is measured by the speed of the car. As such, the alternator has a regulator attached to it, which controls the outputted voltage and ensures it is maintained at a constant.
