BDifficulty 2/5

In a combustion-engine car with a conventional alternator, which component generates alternating current that is rectified to direct current to supply the electrical network and recharge the battery?

Correct answer

Alternator.

The alternator converts mechanical energy into electrical energy. It generates alternating current, which the rectifier converts to direct current for the network and battery. The battery stores energy chemically and can supply direct current; it is incorrect to say it provides no electrical energy. The regulator controls voltage.
