Is the car battery only source of electrical power in your car?

No, the car battery is not the only source of electrical power in a car. While it provides the initial power to start the engine, the alternator is the primary source of electrical power once the engine is running.

Here's how it works:

* Battery: The battery stores electrical energy and provides the initial power to start the engine.

* Alternator: Once the engine is running, the alternator uses the mechanical energy of the engine to generate electricity. This electricity charges the battery and powers all the electrical components in the car, such as headlights, radio, power windows, and more.

So, the battery acts as a reservoir and the alternator is the power plant. They work together to ensure a continuous supply of electrical energy to the car.
