Does a car alternator produce a lot of electricity?

My car battery died while I was at my friend’s house the other day but we figured out how to jumpstart it—thanks to some youtube videos. The video suggested driving around so the alternator can charge the battery. How much electricity does a car alternator produce?

It can be scary when your car doesn’t start so we’re glad to hear your car is up and running again! Yes, the alternator charges the vehicle while you drive, and in good condition it should produce about 13.5 to 15 volts of electricity.
It’s good to make you your alternator is in good condition as it provides much of the electricity to the car’s battery. If your alternator is producing less than 13 volts, be sure to get it checked out as this can cause problems with keeping your battery charged and functioning properly.
