Generator heads and alternators convert mechanical energy into electrical energy. Generators and alternators differ by operation and electrical output, but function via the same ...

There are a few key differences between alternators and generators. Generators have not been used on vehicles since the 1950s. Alternators replaced generators at that time to save weight.

DC The output of the generator head is rectified to produce DC current, such as in an automotive alternator, or uses split rings to produce a current that flows in only one direction. Single Phase AC ...

As the rotation continues and that side of the coil moves down, the induced potential difference reverses direction. This means that the alternator produces a current that is constantly changing.
