Once you start it, yes. Electricity is supplied to a running vehicle by the alternator.

How long do you run your car after a a car jump?

I assume you mean how long to charge the battery. You should never let the alternator charge a dead battery if possible. The alternator is designed to keep the battery charged but not to charge a dead battery. You put a strain on the alternator and it can cause a diode to burn out. Drive home and then put a battery charger on the battery to fully charge it.


Can you charge a dead battery by getting a second car that is running take the good battery out of the running car and put the dead battery into the running car as a means of charging it?

No, this will place a very heavy load on the alternator of the car and may result in burning out the diodes of the car charging the battery. You could easily ruin the alternator. Purchase a battery charger and charge the dead battery with that. Alternators are not made to charge dead batteries.
