I understand. Almost all modern vehicles use a 12-volt electrical system. "Voltage" is electrical pressure, just as pounds per square inch, (psi) is water pressure in a pipe. With electrical systems, it doesn't matter what develops that voltage, the circuitry will operate normally. Think of the generator as an electrical pump, just like a water pump, and the battery is the storage tank, just like a municipal water tower stores water under pressure.
The battery supplies the current, or electrical flow, at first, then the generator takes over once the engine is running. All of the circuitry has no idea where the current is coming from. That can include connecting another vehicle with jumper cables. That would equate to someone opening a huge valve so a nearby town's water system could temporarily supply your town. When you turn on a faucet, you don't know if that water is coming from the pump or one of the storage towers.
Electrical theory can be very difficult to understand, especially for people who learn best by seeing things and manipulating things with their hands. This usually applies to people in trades like auto mechanics. Electrical theory has to visualized because we can't see, but I had real good luck teaching it by comparing everything to something similar that we can see, as with water.
