That is a huge question. Basically.
Most vehicles are made of steel, which conducts electricity, so, to save money and complexity, the bodywork is used as one of the conductors of a circuit. Usually the Negative pole.
Now only one wire need be used to supply a device through a fuse for protection and a switch for control. The return then comes back through the chassis, sometimes referred to as earth or ground, although this is NOT a safety earth, but simply the return path, negative pole.
The battery is there primarily to start the engine, but also provides power to devices when the engine is not running (for a limited time).
As soon as the engine starts, the alternator takes over. The battery is charged, to put back what was taken in starting the engine and then the alternator continues to provide all electrical power, while the engine is running. All the control for this process is contained in the rectifier pack, built into the alternator.
A red light on the dashboard gives a warning when the alternator is failing to provide this service.
All devices are connected in parallel with the 12v system. Some return (-ve) lines are connected together before being 'earthed' to the body via tab and screw/bolt, to return back to the battery.
A lot of faults occur when rusty or corroded steel prevents a proper circuit back to the battery. When this happens the earth is found through other devices and can cause some very strange symptoms.

∙ 12y agoelectric cars pretty much work by a series of battery under the seat of the car, batteries itself weighing some 300 pounds tho in recent times the same battery is getting better one day we will be able to go 1000 miles on a single charge then only then the oil companies will have to sell gasoline at 1 USD least hopefully

What are all of the hybrid electric cars?
Hybrid cars are not the same as an electric car. Electric cars run on electric power exclusively, while hybrid cars use a combination of electric energy and another fuel to run.
When were electric cars available?
The first electric cars appeared in the 1880s.
Do car shops work on electric cars?
I think that the one of the things that electric cars should work in car shops is one of the external parts of an electric car like wheels or chassis. The engine of an electric car doesn't need to be work or fixed anymore in a car shop since it is only battery operated car. You only have to recharge it so you can make it start and operate again.
What are the effects of electric cars?
Electric cars reduce the amount of fuel-dependent cars on the road. As more electric cars are produced, the US will need fewer barrels of gas.
What is the population of Liberty Electric Cars?
The population of Liberty Electric Cars is 40.
When was Liberty Electric Cars created?
Liberty Electric Cars was created in 2007.
Why have gasoline powered cars not been entirely replaced by electric cars?
Electric cars have a limited driving range.
How are electric cars different than hybrid cars?
Electric cars are electric, hybrids are gas, and electric.
Are hybrid cars different than electric cars?
Unlike Electric Cars, Hybrid Cars don't need an outlet to charge battery
Why electric cars over gasoline cars?
I don't pick electric over gas.
How do battery cars work?
They use the DC power from the batteries to run an electric motor to power the vehicle.
The Motor of Electric Cars?
One of the reasons electric cars have risen in popularity is due to their motors. The motors of electric cars are powered by an electric motor rather than a gasoline engine. The motors of electric cars allow you to save money on gasoline and still accelerate at high speeds.
