Title, why can we drive for hours and hours on end, with headlights, radio, a/c, etc. (besides stopping for gas, bathroom breaks) But when we leave a light on for as much as an hour, the car battery will pretty much die instantly.
In: Engineering
This is because while the engine is running it not only drives the wheels, but turns an electrical generator called an alternator. This produces electricity to operate the electrical systems of the vehicle as well as recharging the car’s battery. Effectively while the engine is running you are not using the battery for electricity but rather gasoline.
