With just the key on, the alternator does nothing. With the engine running, a belt drives a pulley on the alternator. Giving the simplest explanation, that pulley is connected to a rod which turns magnets inside a field of copper wiring. That produces electricity. That electricity is alternating current. So it then goes through a diode which converts it to direct current. Then it goes through the voltage regulator, which ensures that your car's battery doesn't get cooked from overcharging. The alternator keeps the battery charged, and that supplies electrical power to vehicle systems.

Why does the alternator light come on when you shut the key off?
The alternator light goes out on starting the engine when both the ignition source, and alternator are producing positive voltage. When the ignition switch is turned off, the engine, and of course, alternator are still turning momentarily. The alternator is then still producing positive voltage, while the 'off' ignition switch has assumed a negative state, creating a closed + - circuit, allowing the lamp to light. This is a very normal state, and has occurred for many decades, even back to the days of cars running generators, prior to the alternator. Absolutely nothing to fear.
