@Naveen thakre is right. i.e.. When engine is off battery supplies electricity for lights, horn, etc and also to crank the engine. After engine starts the alternator recharges the battery and supplies power for the electrical load.

Basically alternator use for convert mechanical energy to electrical energy but in automobile function it use only for continuously recharge the battery.

Basically alternature convert mechanical energy in AC power, then it will be use in various form like battery charging, light, horn etc & dynamometer use for converting mechanical power in DC Energy.
For another query contact me on my email.

There is a basic difference between alternator and dinamo 1. Alternator can produce current with a minimum revolution where dinamo need a maximum revolution to produce current. One thing I would like to mention that alternator and dinamo both are produce alternative current. The alternator has three phase and dinamo has two phase. That is the main cause dinamo need more revolution to produce same amount of current related to alternator.

Battery is used to start the engine. Once the engine starts, Alternator takes charge of powering the whole electrical system. One of the functions is charging battery. Hence I would say the correct answer is to "supply electric power" I. E) [A] in the answer sheet.

No actually the alternator used to recharge the battery and supply the electricity.

Alternator is basically dynamo working due to force of exhaust gases which charges battery, it is use of exhaust gases inside supercharger.

Where exactly is alternator present ?

The main purpose of alternator is to charge the battery but not continuously.
After completion of charging the battery it will cutoff automatically.
If it charge continuously then the charging voltage will be more than the battery voltage then the heavy voltage produced and repelled to the alternator which cause damage to the alternator.

The function of an alternator or a generator is to supply all of the car's electric needs, plus recharge the battery.
A car can run without an alternator or generator, but the battery will eventually go dead.
