This means that the alternator produces a current that is constantly changing. This is alternating current or ac. The output of an alternator can be represented on a potential difference-time ...

In the simplest of terms, an AC generator supplies power directly to a 120-volt circuit to run AC accessories throughout a boat, as well as charge the boat’s batteries (through an AC-to-­DC charger).

The induced voltage produces an induced current if the conductor is connected in a complete circuit. As with all currents, the induced current creates a magnetic field around itself. Note that ...
